Question

What is the volume of the cylinder shown? (Use 3.14 for π .) the height is 21 in and half the diameter is 15 .

Answer 1

Volume = 14,836.5 cubic inches

Explanation:

Cylinder not shown but information given. So we will calculate the volume.

Volume of Cylinder is given by the formula:

`V=\pi r^2 h`

Where

V is the volume

r is the radius (HALF of DIAMETER)

h is the height

It is given in the problem,

Height is 21

h = 21

and

half the diamter (aka radius) is 15

r = 15

Substituting into formula and using 3.14 for
`\pi`, we get the volume:

`V=\pi r^2 h\\V=\pi (15)^2 (21)\\V=(3.14)(225)(21)\\V=14,836.5`

Hence, the volume is:

Volume = 14,836.5 cubic inches
