Other Instructions

The circumference rate is 3.14. The formula for calculating the surface area and volume of the ball, Baidu. By the way, it will certainly be useful in the future, you know!

The formula for this question is a bit tricky and you have to check it yourself.

Sphere surface area = radius X radius x4x π.

Sphere volume = 4/3 x radius X π.

Set of formulas ---

The Code is as follows:

# Include <iostream> using namespace STD; int main () {Double R; CIN> r; cout <4*3.14 * r <"" <(4.0/3) * 3.14 * r; return 0 ;}
