What is the approximate circumference of a circle that has a radius of 90 cm? Use 3.14 for PI and express your answer to the tenths place.

Answer 1

Circumference = 2 * PI * radius
Circumference = 2 * 3.14 * 90
Circumference = 565.2 cm

Therefore, the approximate circumference of a circle with a radius of 90 cm is 565.2 cm.
