Question

A cylinders volume can be calculated by the formula V=pir^2h, where V stands for volume and R for the base radius and H for the cylinders height.

Use the formula to calculate the cylinders volume if its base's radius is 4 meters, and its height is 9 meters

This cylinders volume, in terms of pi, is _________
This cylinders volume, rounded to the hundredth place, is _________

Answer 1

• r=4m
• g=9m

`\\ \tt\hookrightarrow V=\pi r^2h`

`\\ \tt\hookrightarrow v=\pi 4^2(9)`

`\\ \tt\hookrightarrow v=16(9)\pi`

`\\ \tt\hookrightarrow v=144\pi`

`\\ \tt\hookrightarrow v=144(3.14)`

`\\ \tt\hookrightarrow v=452.16m^3`

Answer 2

This cylinders volume, in terms of pi, is 144π m³

This cylinders volume, rounded to the hundredth place, is 452.39 m³

Explanation:

volume of cylinder:

→ πr²h

→ π(4)²(9)

→ 144π

→ 452.39 m³ ......rounded to nearest hundredth
