Question

The radius of a sphere (in cm) whose volume is 12πcm^3 is
(a) 3
(b) 3√3
(c) 3^2/3
(d) 3^1/3

​

Answer 1

Volume of sphere = 4/3 πr³ cm³

= 12 × π cm³

4/3 × π r³ = 12 × π

r³ = ³√9

r = 3√3 cm

So your answer is option B.

Answer 2

Given, Volume of Sphere = 12π cm³

We know that,

Volume of cube = 4/3πr³,

4/3πr³ = 12π

r³ = 12π/4/3π

r³ = 12 * 3 / 4

r³= 3 * 3

r³ = 9

r = ³√9

r = 3√3 cm
