The circumference of a planet is about 23,000 miles. Find its diameter to the nearest mile.
Circumference = \(\pi d\)
We know that the circumference in here is equal to 23000 miles.
23000 = pi x d
pi will be approximated to 3.14
23000 = 3.14d
divide both sides by 3.14 to get
about 7325 as the diameter
Circumference=\(\pi D\)
23000=3.142D
D=\(\frac{23000}{3.142}\)
D=7320.17
D=7320 miles
