The Moon has a surface area of approximately 14650000 miles squared. Estimate its radius to the nearest mile. What is the radius?
We know that the formula for the surface area of the sphere is given by :
SA = 4r^2 * pi such that r is the radius.
Given that SA = 14,650,000 miles^2
We need to find the radius.
==> We will substitute into the equation.
==> 14,650,000 = 4r^2 * pi
Now we will divide by 4pi.
==> r^2 = 14,650,000/ 4pi = 1165809.9581
Now we will take the square root.
==> r= 1079.72 = 1080 miles ( approx.)
Then the radius of the moon to the nearest mile is 1080 miles.
