What is the surface area of a sphere with a circumference of 50 ft?

Firstly, calculate for the radius from the given circumference. The equation for circumference (C) is, 
 
                                          C = 2πr     ; r = C/2π

Substituting the given circumference, 
 
                                                r = 50ft/2π = 25/π ft

The area for the solving the surface area of a sphere is calculated through the equation,
                             SA = 4πr²    =     4π(25/π)²    =     795.77 ft²

Therefore, the surface area is approximately 795.77 ft².
