The radius of a moon is 747 miles. use the formula for the radius r of a sphere given it's surface area a, r=√(a/4π) , to find the surface area of the moon. ! : (

Fill in the numbers you know and solve for the one you don't know.

747 = √(A/(4π))

To undo the square root, square both sides

558,009 = A/(4π)

To undo the division by 4π, multiply by 4π

7,012,147.9 = A

The area of the moon is about 7,012,148 square miles.
