Question

Find the radius of a sphere if its volume is 904.32 cubic cm. (π = 3.14)

Answer 1

Let the radius of the sphere be r cm.

Volume of the sphere = 904.32 cm³

∴ `4/3`πr³ = 904.32 cm³

⇒ r³ = `[ 904.32 xx 3]/[4 xx 3.14]`

⇒ r³ = 216

⇒ r³ = (6)³

⇒ r = 6 cm

Thus, the radius of the sphere is 6 cm.
