Question

The circumference of a circular pond is 654 feet.Whats the diameter at a rate of 6 feet per second?

Answer 1

To find the answer we need to find the raduis

Circumference = 2πr
r=$\frac{Circumference}{2 \pi }$
r=$\frac{654}{2 \pi }$
 = 104.08

The diameter is 2r, hence the diameter is 208.16

If the rate to cross is 6ft. per second, time can be found by dividing the raduis by 6

It would take 34.7 seconds
