The radius of a sphere is 21cm. If s and v represent the curved surface area and volume respectively, what is s : v? (take π = 3.142)

Curved Surface area of a sphere: 4πr²
Volume of a sphere : 4/3 πr³

If you input the value of the radius as 21, you'll get 5,544 and 38,808 respectively.

Curved Surface area of a sphere: 4πr²
Volume of a sphere : 4/3 πr³
4πr² : 4/3 πr³
Divide both sides by 4πr²
1: r/3
r=21
=1:21/3
=1:07
Answer is B.
