Question

the surface area of a sphere is 4 Pi R Square where R is the radius of the sphere is radius of the sphere is doubled then the surface area of the square will be

Answer 1

Answer:

16πR

Step-by-step explanation:

In this situation  r= 2R

So the surface area should be

Surface area= 4πr²

                     = 4π(2R)²

                      = 4π(4R²)

                       = 16πR²
