Hello everyone, i'm a pre-cal student. Starting calculus as we approach the end of the year and i'm stumped on this extra credit problem. I'm trying to find the area of this infield using riemann sums. We were told to find the area inside of the black lines. These black lines start at home plate, run on both foul lines, and then border the long curve at the top.

Additional info my teacher gave, the equation of the grass line is y = sqrt(95^{2}- x^{2}) + 60.5

Also, the equation of the foul line (the one on the right side) is y = x. The length of the foul line to the grass line is 127.6 feet.

Any help would be appreciated
