Question

a museum groundskeeper is creating a semicircular garden with a diameter of 30 feet. there will be a fence around the garden. The fencing cost $9.25 per linear foot. About how much will the fencing cost all together?

Answer 1

713.396

Explanation:

The formula for the circumference of a semicircle is 1/2(pi x d) + d which means that the circumference for this semicircle would be 1/2(pi x 30) + 30 = 77.124. You then multiply this number by 9.25 and you get 713.396.

I hope this is right and helps.
