Question

The diameter of the moon is 3480km

What is the surface area of the moon?

Answer 1

If you want to do it mathematically, here is the way:

Simply use the Surface Area formula for a sphere since the moon is a sphere:

SA=4pi(r^2)

We need to find the radius, so the radius is half the diameter:

r=3480/2
r=1740

Now justplug this into the formula:

SA=4pi(1740^2)
SA=4pi(3027600)
SA=38045943.67

The surface area of the moon is approximately 38045943.67 km^2
