Question

volume and surface area of a sphere is equal.Find the radius of the sphere​

Answer 1

Answer:

Let the radius be x.

Step-by-step explanation:

4 * 22/7 = r*r = 4/3* 22/7*r*r*r

We canceled both 22/7 and 4

r*r = 3r*r*r

R = 3units

If u liked my answer mark me as brainliest

Answer 2

let volume be V and Surface area be A

V= 4/3 πr³ and A=4πr²

according to the question

4/3 πr³ = 4πr²

πr³ = 3πr²

r= 3πr²/r²

r= 3π = 9.42cm
