Question

Y’all I’m so confused, I got 38792.3. What am I doing wrong?

Answer 1

`\textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=42 \end{cases}\implies V=\cfrac{4\pi (42)^3}{3}\implies \stackrel{ using~\pi =3.14 }{V\approx 310181.76}`

Answer 2

38,772.72

Explanation:

The formula for a sphere is

V=4/3 pi r^3

=4/3 3.14 21^3

=4/3 3.14 9,261

=4/3 29,079.54

=38,772.72
