    Step-by-step explanation:

    This equation gives circumference (24900 miles). Knowing this the formula to start off finding radius is

    c=2\pi r

    we know c(circumference) and we know pi(3.1415926535…)

    so move the numbers to isolate r(radius) to look something like this

    \frac{c}{2\pi } =r

    input the known values then solve.

    \frac{24900}{2\pi } =r

    \frac{12450}{\pi } =r

    3962.95808... =r

    (round this to whatever value you are looking for)

    Hope This Helps 🙂
