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

Answer:

volume = 33.5 in³

Step-by-step explanation:

Formula:

$\sf volume \ of \ a \ cone=\dfrac13\pi r^2h$

Given:

• r = 2 in
• h = 8 in
• π = 3.14

Substituting the given values into the formula:

$\sf \implies volume=\dfrac13 \times 3.14 \times 2^2 \times 8$

                  $=\dfrac13 \times 3.14 \times 4 \times 8$

                  $\sf =33.49333333...$

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