the diameter of the earth's moon is on average 3.8 x 10 to the 8th power m. use the formula a equals 4 pi r to the second power to find the approximate surface area

The Surface area of the moon is  

Step-by-step explanation:

Given:

Diameter of the moon =  3.8 x 10 to the 8th

To Find :

The surface area of the moon = ?

Solution:

The moon is in the shape of of the sphere .

So the surface area of the moon = surface area of the sphere

The surface area of the sphere  =

Where r is the radius of the sphere

Radius , r =

r =  

r =  

Now the surface area of the moon with radius r =   is
