B. 565.2 cm

The formula for calculating the circumference of a circle is C = 2πr, where r is the radius of the circle. Given that the radius is 90 cm, plugging this into the formula we get:

C = 2 * 3.14 * 90
C = 565.2 cm

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