Question

In a sport called sphereing, a person rolls down a hill inside an inflatable ball surrounded by another ball. The diameter of the outer ball is 12 feet. Calculate the surface area of the outer ball.

Answer 1

So you have to get the radius to get the surface area! 

So do the diameter (12) divided by 2. 12/2=6

So that equals 6 So now you do [tex] 4 \pi r^{2} [/tex]
So now your answer would be:
452.39
