A cone has a volume of 47.1 cm³ and a radius of 3 cm what is its height?

Answers

Answer 1

Radius of cone ( r ) = 3 cm,

Curved surface area of a cone= 47.1 cm²

Curved surface area of a cone= πrl

47.1 = πrl

47.1 = 3.14 × 3 × l

l = 47.1 / (3.14 × 3)

l = 15.7 / 3.14= 1570/314= 5 cm

slant height (l) = 5 cm

Height of a cone (h) = √(l²) - (r²)

h = √ 5² -3²

h = √ 25 - 9 = √ 16 = 4 cm

h = 4 cm

Volume of cone= ⅓(πr²h)

= ⅓(3.14 × 3 × 3 × 4)

= 3.14 × 12= 37.68 cm³

Hence, the volume of a cone is 37.68 cm³.

Greg invested $6000 in a bond with a yearly interest of 4%. His total interest on his investment was $1200. What was the length of the investment

Answers

Answer:

5 years

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4%/100 = 0.04 per year,

then, solving our equation

t = 1200 / ( 6000 × 0.04 ) = 5

t = 5 years

The time required to

accumulate simple interest of $ 1,200.00

from a principal of $ 6,000.00

at an interest rate of 4% per year

is 5 years.

An isosceles triangle includes two 72°
angles. Which equation could be used to
find the measure of the third angle?
A X + 72 = 180
B X = 180 - 72
C 72-X= 180
D 180 - 2(72) = X

Answers

I don't understand the options but I will explain it to u!

Step-by-step explanation:

An Isosceles triangle has two equal sides that means , In this question it is given that there are two 72°angles so,

72+72+x =180

(Transpose)

x = 180-(72+72)

x = 180-(144)

Therefore, x= 36

In an isosceles triangle, two sides are equal and their opposite angles are also equal. Then the correct option is D.

What is the triangle?

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

An isosceles triangle includes two 72° angles.

In an isosceles triangle, two sides are equal and their opposite angles are also equal.

And the sum of the angles of the triangle is 180°.

Let the third angle be x. Then we have

72° + 72° + x = 180°

180° - 2(72°) = x

Thus, the correct option is D.

Step-by-step explanation:

1. Make an equation: 12-(-13).

2. Solve the equation. Since there are 2 negative signs (one to the right of 12 and another to the left of 13) they can cancel each other out and they turn into an addition sign. Then, you get 12+13. You can easily solve that and you will get the answer of 25 degrees.

Step-by-step explanation:

p = perimeter

w = width

let the length be l

as we know that

perimeter of rectangle (p).= 2(l+ w)
