Question

the volume of spheare is38808cm find the radius

Answer 1

Given- Volume of sphere= 38808cm³

To find- r = ?

Solution-

⇒We know that volume of a sphere  = 4/3 pi r³

⇒4/3 pi r³ = 38808

⇒pi r³= (38808)3/4

⇒pi r³ = 29106

⇒r³ = (29106)7/22

⇒r³ = 9261

⇒r=∛9261 = 21

∴ So radius = 21cm

Hope it helps!!!

Cheers!!

Answer 2

Step-by-step explanation:

volume of sphere=

$volume \: of \: sphere \: = \frac{4}{3}\pi {r}^{3} \\ \: \: \: \: \: \: \: \: \: \: \: 38808= \frac{4}{3} \times \frac {22}{7} {r}^{3} \\ \: \: \: 38808 \times \frac{3}{4} \times \frac{7}{22} = {r}^{3} \\ {r}^{3} = 9261$
