Question

A sphere has a radius of 6 inches and a surface area of 144π in2. The radius of the sphere will be doubled. How will this effect the surface area of the sphere?

Answer 1

Answer:

it quadrupled

Step-by-step explanation:

Answer 2

FORMULA FOR SURFACE AREA OF SPHERE = 4 pi r^2 

r = 6 " area = 4 pi X 6 X 6 = 144 pi " squared 

r = 12 " 

area = 4 X pi X 12 X 12 = 576 pi" squared 


ANSWER Area will be 4 times the original
