Question

the radius of a sphere whose volume is 12πcm^3

Answer 1

Answer:√3 = radius of sphere

Step-by-step explanation:

Volume of sphere = 4/3πr^3

Given volume = 12πcm^3

Now,

4/3πr^3 = 12 * π { here I cancelled out 'π' }

r^3= 12 * 3/4

r^3= 3 * 3

r= √9

r= √3

Answer 2

Answer:

volume of sphere = 4/3 πr^3

therefore,

12 π cm^3 = 4/3πr^3

π will be cancelled

therefore, 4/3 r cube = 12cm cube

r^3 = 12×3/4

r^3 = 9

therefore radius = √3
