Answer: The area of the cross section is 81pi meters.
Since we are given the circumference, we can write and solve an equation about the diameter.
C = pi(d)
18pi = pi(d)
18 = d
Since the diameter is 18, the radius is half of that or 9 meters.
Now, plug 9 as the radius into the area formula.
A = pi(r^2)
A = pi(9^2)
A = 81pi
b) 8
they were asking you about the rate of increase in students per year
so you take increase in students/years= (224-120)/(2005-1992)=104/13=8
