The formula for the circumference of a circle is:
C = 2πr
where C is the circumference and r is the radius.
Given that the circumference is 100.48 kilometers, we can substitute this value into the formula:
100.48 = 2πr
Dividing both sides of the equation by 2π, we get:
r = (100.48) / (2π)
Using π ≈ 3.14, we can calculate the radius:
r ≈ (100.48) / (2 * 3.14)
r ≈ 100.48 / 6.28
r ≈ 16.00
Rounding the answer to the nearest hundredth, the circle's radius is approximately 16.00 kilometers.
