Question

f a sphere’s radius is quadrupled, what is the corresponding change in surface area?

Answer 1

The surface area is multiplied by 16.... THAT THE ANSWER

Answer 2

sa of sphere = 4(pi)r^2 = A
so if we make the radius 4 times
sa = 4(pi)(4r)^2 = 4(pi)(16r^2)
can you figure out now?

Answer 3

yes!!
