How do you find the circumference of a sphere?
The formula is: 4*pi*R^2 (* means times/multiply; and ^ means exponent) :)
To calculate the circumference of a sphere,calculate the radius of the sphere. Then, raise the radius to the second power by multiplying it with itself. After that, multiply this number by Pi and then multiply this result by 4.
C=2pi times r. Area=4pi times r^2
