Apile of sand on the beach has the approximate shape of a cone with a diameter 28 in. and a height of 11.75 in.

what is the best approximation for the volume of the pile of sand?

a 2411.7 in³
b 3617.5 in³
c7235.1 in³
d9646.8 in³

A) Volume of the pile of sand is 2411.7 in³ .

Step-by-step explanation:

Given : A pile of sand on the beach has the approximate shape of a cone with a diameter 28 in. and a height of 11.75 in.

To find : volume of the pile of sand.

Solution : We have given that diameter of cone  = 28 in.

                                                  height = 11.75 in.

Radius =  .

Radius = 14 in.

Volume of cone  = .

Volume of cone =  .

Volume of cone  = 2410.47

Volume of cone ≈ 2411.7 in³.

Therefore, A) Volume of the pile of sand is 2411.7 in³ .
