Question

the numerical value of volume of a sphere is five times of the numerical value of its surface area. the radius of sphere will be ​

Answer 1

Answer:

4/3pai r cube is the he volume of the the sphere

Answer 2

Answer:

Let the area of sphere be X

4πr²=X

and given that , volume of sphere is 5 times of area

5(4πr²)=4/3πr³

9πr²=4/3πr³

27r²=4r³

27/4=r³/r²

r=6.75
