Question

What is the radius of the sphere?

Answer 1

radius ( r) = 1 cm

The volume (V) of a sphere is calculated using the formula

V =
`(4)/(3)`πr³

here V is given as V =
`(4)/(3)`π

Equating gives

V =
`(4)/(3)`πr³ =
`(4)/(3)`π

dividing both sides by
`(4)/(3)`π, gives

r³ = 1 ( take the cube root of both sides )

r = ∛1 = 1
