a circular swimming pool has a radius of 15 ft. There is all away around the pool thats is 3 ft wide. what is the circumference of the outer edge of the pool
Since the radius is 15 feet you would multiply by 2 to get the diameter which is 30, adding the 3 feet on each side gives you 36, then using the formula, C=2(pie)r you would get C=113.1
