The surface area of a cylinder can be found by adding the areas of the top and bottom circles, as well as the area of the side (lateral) surface.
The radius of the cylinder is 1 and one fourth centimeters, which can be written as 5/4 cm. The height of the cylinder is 3 and three fourths centimeters, which can be written as 15/4 cm.
The area of each circle is πr^2, where r is the radius. So, the area of the top and bottom circles is:
2π(5/4)^2 = 25/2 π square centimeters
The lateral surface area of a cylinder is given by the formula 2πrh, where r is the radius and h is the height. So, the lateral surface area of the cylinder is:
2π(5/4)(15/4) = 75/2 π square centimeters
Therefore, the total surface area of the cylinder is:
25/2 π + 75/2 π = 100/2 π = 50 π square centimeters
So, the exact surface area of the cylinder in terms of π is 50π square centimeters. None of the given options matches this answer.

A. −4.26
B. −12.98
C. 13.41
D. 259.26
Answer: -41.66
Step-by-step explanation:From the question, we have the following parameters that can be used in our computation:
negative 17 plus the quantity negative 3 and seven tenths plus 9 and 15 hundredths end quantity divided by 5 all times 4 squared minus 4 and 7 tenths
Rewrite properly
So, we have
(-17 - 3.7 + 9.15)/5 * 4² - 4.7
Evaluate the sum and the difference in the expression
So, we have
-11.55/5 * 4² - 4.7
Evaluate the exponent and the quotient
-2.31 * 16 - 4.7
So, we have
-36.96 - 4.7
Evaluate
-41.66
Geological processes are events that happen on Earth over and over again throughout time. How can you tell that the formation of volcanoes is a geological process that will repeat over time?
The formation of volcanoes is considered a geological process because it is a natural occurrence that results from the movement and interactions of tectonic plates beneath the Earth's surface.
The following are some ways that suggest the formation of volcanoes is a geological process that will repeat over time:Plate tectonics: The movement and collision of tectonic plates are the main drivers of volcanic activity on Earth. As the plates move, they create areas of tension and pressure that can lead to the formation of volcanoes. Since plate tectonics is an ongoing process, the potential for the formation of volcanoes will continue over time.Volcanic history: The geological record of the Earth shows that there have been many volcanic eruptions throughout the planet's history. This suggests that the formation of volcanoes is a recurring process that has happened repeatedly in the past and will continue to occur in the future.Active volcanoes: There are currently more than 1,500 active volcanoes on Earth, which is a clear indication that volcanic activity is an ongoing process. These active volcanoes are located in regions that are associated with tectonic plate boundaries and hotspots, which are also evidence that volcanic activity is a geological process that will continue to occur over time.Geological surveys: Geologists can study the geological features of an area to identify whether it is prone to volcanic activity. For example, if an area has a history of volcanic eruptions or contains volcanic rock formations, it suggests that the area is likely to experience future volcanic activity.Overall, the combination of plate tectonics, volcanic history, the presence of active volcanoes, and geological surveys provide strong evidence that the formation of volcanoes is a geological process that will continue to occur over time.

You have a bag of marbles with 630 marbles in it: 110 red, 230 green, and 290 blue. You pull out 1 marble, record the color, and replace it.
After you do this 100 times, the table shows the number of times each color was drawn:
Red Green Blue Total
21 35 44 100
Give exact, reduced answers.
a) What is the theoretical probability of drawing a blue?
b) What is the experimental probability of drawing a blue?
Answer:
a) The theoretical probability of drawing a blue marble is the ratio of the number of blue marbles to the total number of marbles in the bag, which is:
P(blue) = number of blue marbles / total number of marbles
= 290 / 630
= 29 / 63
So the theoretical probability of drawing a blue marble is 29/63.
b) The experimental probability of drawing a blue marble is the ratio of the number of times a blue marble was actually drawn to the total number of trials, which is:
P(experimental blue) = number of times a blue marble was drawn / total number of trials
= 44 / 100
= 11 / 25
So the experimental probability of drawing a blue marble is 11/25.

Write the equations of each line in slope-intercept form. (y=mx+b)
Answer:
The equation would be y = -2x + 19
Step-by-step explanation:
To find this, we can use the point and the slope in point-slope form. The we solve for y.
y - y1 = m(x - x1)
y - 7 = -2(x - 6)
y - 7 = -2x + 12

What is the measure of angle A in this triangle?
Enter your answer in the box.
m∠A=
°
I am to believe the answer is 50 degrees
Answer: hope this helps ♡
m∠A= = 50°
Step-by-step explanation:
Triangle = 180°
A + B + C = 180°
(2x-10)° + (x+30)° + 70° = 180°
2x° + x° + 30° - 10° + 70°= 180°
3x° + 90° = 180°
3x° + 90° - 90 = 180° - 90
3x = 90°
3x ÷ 3 = 90° ÷ 3
x = 30°
m∠A= (2×30-10)° = (60-10)° = 50°

THE PROBLEM IS , y divided by 6 x 6 = 3 x 6
SO THEN ITS ASKING ME "IF WE DIVIDED BY 6 AND THEN MULTIPLY BY 6, WHat IS LeFT???
PLEASE HEP ME
Answer:
Step-by-step explanation:
y divided by 6x6=3x6
1. multiply first
a) 6x6 = 36
b) 3x6=18
c) y/6 times 6 =3 x6 .....make it a fraction Y over 6 times 6 over 1
d) y/6 times 6/1----cross off the two 6's
Now: y=3x6
y=18
6 times 6 = 36 and 6 times 3 = 18
36 = 18
So, 18 divided by y = 36
so, 18 times 36 = 648
Hence, y is divided by 648 to get 6 x 6
Abdul wants to rent a boat and spend at most $35. The boat costs $8 per hour, and Abdul has a discount coupon for $5 off. What are the possible numbers of hours Abdul coult rent the boat?
Use t for the number of hours, write your awnser as an inequality solved for t.
Answer:
Abdul can rent the boat for at most 5 hours.
Step-by-step explanation:
Let's call the number of hours Abdul rents the boat "t".
The cost of renting the boat without the discount coupon is $8 per hour, so the cost would be 8t dollars.
With the discount coupon, the cost of renting the boat would be 8t - 5 dollars.
We know that Abdul wants to spend at most $35, so we can write the inequality:
8t - 5 ≤ 35
Solving for t, we get:
8t ≤ 40
t ≤ 5
Therefore, Abdul can rent the boat for at most 5 hours.

568.50 x 0.2
need help asap!!!!
Answer:113.7
Step-by-step explanation:
Answer:
113.7
Step-by-step explanation:
To calculate 20% of 568.50, you can convert 20% to a decimal by dividing it by 100.
20% ÷ 100 = 0.20
Then, you can multiply the decimal by the original value to find the answer:
0.20 x 568.50 = 113.70
Therefore, 20% of 568.50 is 113.70.

yolanda measures the depth of the water in a reservoir. In one week the depth changes from 2,366.74ft to 2,354.63.ft. what rational number represents the average change in the depth each day? Show your work.
Answer:
Step-by-step explanation:
To find the average change in depth each day, we need to divide the total change in depth by the number of days.
Total change in depth = 2,366.74 - 2,354.63 = 12.11 ft
Number of days = 7
Average change in depth each day = Total change in depth / Number of days
= 12.11 / 7
= 1.73 (rounded to two decimal places)
Therefore, the rational number that represents the average change in depth each day is 1.73 ft per day.

(picture)
Answer:

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 =55
The way to calculate triangle numbers is to add the corresponding number.
For example, 1 is a triangle 1 + 2 is a triangle 1 + 2 + 3 is a triangle so on and so forth.
Triangle numbers would be 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, 66, 78, and 91
