Question 131827: The problem reads:
The surface area of a sphere is given by S=4(pi)r^2, where r is the radius and (pi) is 3.14. Find the radius of a sphere whose surface area is 748 square centimeters.

I do not know how to work this problem, because I am used to finding the surface area.

Solve the formula for r:
S=4%2Api%2Ar%5E2

r%5E2=S%2F%284%2Api%29

r=sqrt%28S%2F%284%2Api%29%29

I trust that you can plug in the value for S and do the arithmetic.
