What is the approximate circumference of a circle that has a radius of 90 use 3.14 for pi and express your answer to the tenths place

1 answer

The circumference of a circle is calculated using the formula C = 2 * π * r where r is the radius of the circle.

C = 2 * 3.14 * 90
C = 564.6

Therefore, the approximate circumference of a circle with a radius of 90 is 564.6 units.
