Question

Find the volume of the cone. Round to the nearest tenth.

answer choices:
10,306.0 m³,
763.4 m³,
41,224.0 m³,
20,612.0 m³

Answer 1

20,612.0 m³

Explanation:

Formula for area of cone: 1/3h
`\pi`r²

Since there is a 45 - 45 - 90 triangle and 27 meters is one of the congruent sides, the other side must also be 27 meters.

Then, just plug it in.

1/3 x 27m x 3.1415... x (27m)²

= (27m)³ x 3.1415 x 1/3

= 20,611.3815m³

≈ 20,612.0 m³
