The city has decided to build a circular outdoor amphitheater in the new park. The architects would like to surround the amphitheater with a 1 foot high brick wall and lay turf inside. They would like the diameter of the amphitheater to be 140 feet. The city has provided a budget of $60,000 for this project.
a. The brick wall is estimated to cost $80.00 per foot. What is the cost for the brick wall? Use 3.14 for ฯ.
b. The turf is estimated to cost $3.00 per square foot. What will be the cost for the turf? Use 3.14 for ฯ.
c. Can the city complete this project and stay within the budget? Explain.

Prove (a) cosh2(x) โ sinh2(x) = 1 and (b) 1 โ tanh 2(x) = sech 2(x). solution (a) cosh2(x) โ sinh2(x) = ex + eโx 2 2 โ 2 = e2x + 2 + eโ2x 4 โ = 4 = . (b) we start with the identity proved in part (a): cosh2(x) โ sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 โ sinh2(x) cosh2(x) = 1 or 1 โ tanh 2(x) = .
