Question

find the surface area a planet if its circumference is about 18,000 miles long. Round to the nearest thousand square miles

Answer 1

The surface area of the planet is 103,184,713.4 miles².

What is the surface area?

A planet has the shape of a sphere.

The first step is to determine the radius of the planet from the circumference.

Radius = circumference / (π x 2)

18,000 / (3.14 x 2) = 2,866.24 miles

Surface area of a sphere = 4πr²

4 x 3.14 x ( 2,866.24²) = 103,184,713.4 miles²
