Answer 1

Answer:

The radius of sphere is 9m.

Step-by-step explanation:

Given that the formula of volume of sphere is V = 4/3×π×r³ and it is 972π m³. So you have to substitute the value into the formula, in order to find radius :

$v = \frac{4}{3} \pi {r}^{3}$

Let V = 972π,

$972\pi = \frac{4}{3} \pi {r}^{3}$

$972 = \frac{4}{3} {r}^{3}$

$972 \div \frac{4}{3} = {r}^{3}$

${r}^{3} = 729$

$r = \sqrt[3]{729}$

$r = 9metres$

Answer 2

Answer:

r = 9 m

Step-by-step explanation:

The volume of a sphere is defined as:

$V = \frac43 \pi r^3$

if this is equal to 972π, then r³ = 972 * 3/4

so r = ∛729 = 9
