Question

What is the volume of a sphere with a radius of 2 cm? use 3.14 for π. round to the nearest hundredth, if needed?

Answer 1

So the formula of the volume of a sphere is $V= \frac{4}{3} *3.14*r^3$

Just plug in 2 in the r variable and solve:

$V=\frac{4}{3} *3.14*2^3 \\ V=\frac{4}{3} *3.14*8 \\ V=\frac{4}{3} *25.12 \\ V=33.49$

Your volume is 33.49 cm^3
