how do i find the surface area of a sphere with the radius is 8?

OpenStudy (anonymous):

What is the formula for the surface area of a sphere?

OpenStudy (anonymous):

area=4pie*radius cubed

OpenStudy (anonymous):

I don't believe that's correct. I think it's r squared, not cubed.

OpenStudy (anonymous):

So you know the radius, plug it into the formula and find the surface area.

OpenStudy (anonymous):

your right it is r squared
