Two cylinders are shown below. Find the volume of each cylinder. Use 3.14 for pie. Enter your answers rounded to the nearest hun

Alchen [17]

Given:

For cylinder P: radius = 4.25 in. and height = 14 in.

For cylinder Q: radius = 7 in. and height = 8.5 in.

To find:

The volume of each cylinder.

Solution:

Volume of a cylinder is

$V=\pi r^2h$

where, r is radius and h is height. Use 3.14 for $\pi$ .

Using the above formula, the volume of cylinder P is

$V_P=(3.14)(4.25)^2(14)$

$V_P=794.0275$

$V_P\approx 794.03$

Using the above formula, the volume of cylinder Q is

$V_Q=(3.14)(7)^2(8.5)$

$V_Q=1307.81$

Therefore, the volume of cylinder P is 794.03 sq. in. and volume of cylinder Q is 1307 sq. in.
