Question

The diameter of Earth’s moon is on average 3.8 x 10ˆ8 m. Use the formula A= πrˆ2 to find the approximate surface area. (Use 3.14 for the value of π.)

Answer 1

Step-by-step explanation:

Diameter of earth's moon =3.8*10^8 m

radius =3.8/2*10..^8 m

radius,r=1.9*10^8 m

surface area,A=πr^2

A=3.14*1.9*10^8*1.9*10^8

A=11.3*10^16

A=1.13*10^17 m^2
