Question

The radius of sphere (in cm) whose volume is 12pie cm3, is
A)3
B)3root3
C)3^2/3
D)3^1/3

Answer 1

Answer:

3 is the answer as the formula is 4/3πr^3

Answer 2

Answer:

answer is 3

Step-by-step explanation:

$volume \: of \: sphere \: = \: \frac{4}{3} \pi {r}^{3} \\ 12\pi \: \: \: \: = \frac{4}{3} \pi {r}^{3} \\ 12 = \frac{4}{3} {r}^{3} \\ 12 \times 3 \div 4 = {r}^{3} \\ 36 \div 4 = {r}^{3} \\ 9 = {r}^{3} \\ 3 = r$
