Question

$\text{The volume of a sphere of radius 2r is}$

$\left(a\right)\frac{32\pi r^3}{3}$

$\left(b\right)\frac{16\pi r^3}{3}$

$\left(c\right)\frac{8\pi r^3}{3}$

$\left(d\right)\frac{64\pi r^3}{3}$

Answer 1

ANSWER:
(a) $\frac{32\pi r^3}{3}$

The volume of the sphere of radius 2r=$\frac{4}{3}\pi (2r{)}^3=\frac{32\pi r^3}{3}$
