A tunnel is constructed with a semielliptical arch. The width of the tunnel is 80 feet, and the maximum height at the center of
the tunnel is 30 feet. What is the height of the tunnel 4 feet from the edge? Round your answer to the hundredths place. 4.01 feet
9.37 feet
13.08 feet
29.85 feet
The reason why is because you first have to add 0.05 and 18 together, and than multiply it by the closes number to 81.20 which is 4, and also it cannot be over 81.20.
