Answer 1

To find the circumference of a circle, we use the formula C = 2 * π * r, where r is the radius of the circle.

Given that the radius of the circle is 90 cm, we can plug this value into the formula:

C = 2 * 3.14 * 90
C = 565.2

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

The correct answer is:
O 565.2 cm
