Question

the radius of sphere in cm whose volume is 12 pi

Answer 1

Answer:

vol of sphere= 4/3π×r^3=12π

4/3 r^3=12

r^3=9

r^3=3^2

r=3^2/3

Answer 2

your answer

volume of sphere = 12 π

$\frac{4}{3}$πr³ = 12 π

(by canceling pi in both LHS and RHS)

$\frac{4}{3}$r³ = 12

r³ = 12×$\frac{3}{4}$

r³ = 9

r = ∛9

radius = ∛9
