On a circular playground, the distance from its center to the edge of the playground is 36 feet. What is the approximate circumference of the playground?
The distance from the center of the circle to the edge is the radius (r) which is given to be 36 feet. The formula for circumference is: [tex]C = 2 \pi r[/tex] Plug in r = 36 to the formula to get: [tex]C = 2 \pi (36) = 72 \pi [/tex] Therefore, the circumference is 72pi.
