Question

What is the volume of this cone? Use 3.14 for π and round your answer to the nearest tenth.

In your answer, give the volume of the cone rounded to the nearest tenth, and then explain how you calculated it.

Answer 1

volume = 33.5 in³

Explanation:

Formula:

`\sf volume \ of \ a \ cone=\frac13\pi r^2h`

Given:

• r = 2 in
• h = 8 in
• π = 3.14

Substituting the given values into the formula:

`\sf \implies volume=\frac13 * 3.14 * 2^2 * 8`

`=\frac13 * 3.14 * 4 * 8`

`\sf =33.49333333...`

`\sf =33.5 \ in^3 \ (nearest \ tenth)`
