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 = $\frac{4}{3}$πr³

here V is given as V = $\frac{4}{3}$π

Equating gives

V = $\frac{4}{3}$πr³ = $\frac{4}{3}$π

dividing both sides by $\frac{4}{3}$π, gives

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

r = ∛1 = 1
