Which sphere has a volume of 0.288Pi in.3? A sphere with radius 0.4 inches. A sphere with radius 0.5 inches. A sphere with radiu

worty [1.4K]

C. A sphere with radius 0.6 inches.

Here is why:

The equation for the volume of a sphere is:

$V=\frac{4}{3} \pi r^3$

We can plug in and solve.

$V=\frac{4}{3}*\pi *0.6*0.6*0.6$

We will multiply everything but leave the 3 to divide later.

So...

$4*\pi *0.6*0.6*0.6=0.864\pi$

Divide by 3.

$0.864\pi /3=$

0.288π
