A cone has a diameter of 12 centimeters and a height of 9 centimeters. Using 3.14 for pi, find the
volume of the cone to the nearest tenth.
A cone has a diameter of 12 centimeters and a height of 9 centimeters. The volume of the cone would be 2034.72 cubic cm.
How to find the volume of a right circular cone?
Suppose that the radius of considered right circular cone be 'r' units.
And let its height be 'h' units.
Then, its volume is given as:
[tex]V = \dfrac{1}{3} \pi r^3 h \: \rm unit^3[/tex]
The right circular cone is the cone in which the line joining the peak of the cone to the center of the base of the circle is perpendicular to the surface of its base.
A cone has a diameter of 12 centimeters and a height of 9 centimeters.
Radius = 12/2 = 6cm
Height h = 9 cm
The volume of the cone
[tex]V = \dfrac{1}{3} \pi r^3 h \: \rm unit^3[/tex]
[tex]V = \dfrac{1}{3} \times 3.14 \times 6^3 \times 9\: \rm unit^3\\\\V = 3.14 \times 648\\\\V = 2034.72 cm^{3}[/tex]
Hence, The volume of the cone would be 2034.72 cubic cm.

Sophia bought a fish tank with the dimensions shown below.
Which is closest to the number of cubic FEET of water needed to fill the fish tank? Hint: There are 1,728 cubic inches in 1 cubic foot.
A
0.8 cubic feet
B
2.5 cubic feet
C
240.0 cubic feet
D
1,440 cubic feet
0.8 cubic feet is closest to the number of cubic feet of water needed to fill the fish tank.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
To find the number of cubic feet of water needed to fill the fish tank
we need to first convert the dimensions of the tank from inches to feet.
since the conversion factor between cubic inches and cubic feet is 1,728.
Length in feet = 20 inches ÷ 12 inches/foot
= 1.67 feet
Height in feet = 12 inches ÷ 12 inches/foot
= 1 foot
Width in feet = 6 inches ÷ 12 inches/foot
= 0.5 feet
The volume of the fish tank in cubic feet is:
Volume = length × height × width = 1.67 feet × 1 foot × 0.5 feet = 0.835 cubic feet
Hence, the number of cubic feet of water needed to fill the fish tank is 0.8 cubic feet, Option A is correct.

7/24
Step-by-step explanation:
(There are many methods to divide fractions, but this is the easiest one in this situation)
7/6 ÷ 4
Dividing something by four is the same as dividing by 4/1, which is the same as multiplying it by 1/4.
So,
7/6 * 1/4
Multiply the denominators.

Find BC.
25
25
B
3x + 4
D 4x - 5 c
Answer:
b) BC = 62
Step-by-step explanation:
since AB and AC equal 25, we know that ΔADB ≅ ΔADC and we can write this equation:
3x + 4 = 4x - 5
4 = x - 5
x = 9
3(9) + 4 = 31
BD = 31
DC = 31
BC = 2(31) = 62
