There are many cylinders with a height of 9inches. Let r represent the radius in inches and v represent the volume in cubic inches what belongs in cell A

Complete question :

There are many cylinders with a height of 9 inches. Let r represent the radius in inches and V represent the volume in cubic inches.

a. Complete the table relating the radius and volume of cylinders with height 9 inches. Write each volume as a multiple of , or round to the nearest cubic inch.

A = 9π in³

B = 36π in³

C = 81π in³

Step-by-step explanation:

Radius, r = 1, 2, 3

Height of cylinder = 9

Volume, V of cylinder : πr²h

For, r = 1

V = π(1)²9 = 9π in³

For, r = 2

V = π(2)²9 = 4*9π in³ = 36π in³

For r = 3

V = π(3)²9 = 9*9π in³ = 81π in³

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.
