Find the radius of a sphere with a volume of 2304 pi cubic centimeters.
Shalnov [3]

Answer:

The radius of a sphere would be 12 cm.

Step-by-step explanation:

The formula for the volume of the sphere =

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

By putting the value of volume we can find the radius of the sphere.

Volume of the sphere = 2304 π cm³

2304\pi =\frac{4}{3}\pi  r^3

2304=\frac{4}{3} r^3

2304\times \frac{3}{4}=\frac{3}{4}\times \frac{4}{3}r^3

2304\times \frac{3}{4}=r^3

576 × 3 = r³

r=\sqrt[3]{1728}

r = 12

The radius of a sphere would be 12 cm.
