What is the appropriate circumference of a circle that has a radius of 90? Use 3.14 for li and express answer to the tenths place
The formula for the circumference of a circle is C = 2πr, where r is the radius.
C = 2 x 3.14 x 90
C = 564.6
So, the appropriate circumference of a circle with a radius of 90 is 564.6 units.
