The surface area of the planet is 103,184,713.4 miles².
<h3>What is the surface area?</h3>
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
