Question

What is the volume of a sphere with radius of 16 inches?

Answer 1

Volume =
$\frac{4}{3} \pi {r}^{3} \\ = \frac{4}{3} \times 3.14 \times {16}^{3} \\ = 17148.59 \ {in}^{3}$

The answer is the first option.

Answer 2

Hey there :)

We know the volume formula of a sphere is:
$\frac{4}{3}$$\pi$ (radius)³

We are given the radius = 16 in
And asked to use 3.14 for $\pi$ 

Apply the formula
V = $\frac{4}{3} (3.14)(16)^3$
   = $\frac{4}{3} (3.14)(4096)$
   = 17,148.58667
   ≈ 17,148.59 in³

Your answer will be the first option
