solve the equation for A , then substitute in the value for r
squaring ... r^2 = A / (4 π)
multiplying by 4π ... 4 π r^2 = A
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. Please help ASAP!!!!! :(
