Answer 1

Answer:

A sphere with radius r has a volume of 4 3 π r 3 \frac{4}{3} \pi r^3 34πr3 and a surface area of 4 π r 2 4 \pi r^2 4πr2. A sphere has several interesting properties, one of which is that, of all shapes with the same surface area, the sphere has the largest volume.

Answer 2

Step-by-step explanation:

the total surface area of sphere = 4πr²
