Answer 1

Explanation:

your teacher even wrote all the formulas there.

you have all numbers.

so, all that is left is to take the calculator and type things in.

so, what was your problem here ?

I cannot tell you much more than what is written in your question already.

the only thing : the radius (needed in the formula) is half of the diameter.

so,

V = 4/3 × pi × r³ = 4/3 × pi × (16/2)³ = 4/3 × pi × 8³ =

= 4/3 × pi × 512 = 2048/3 × pi = 2,144.660585... ft³ ≈

≈ 2,144.7 ft³
