The surface area of the sphere is =
Explanation:
The area of a sphere can be calculated using this formula:
However, we have a little problem: we do not have our radius yet to utilize in the formula above.
We can get our radius from the circumference of the circle which has been given to us.
circumference =
We now have our radius. we can input it into equation 1 above
The Surface area of sphere =
