A cylindrical barrel has a radius of 11.25 in and a area of 33.5 in. Use 3.14 as pi to find the circumference and area, to the nearest hundredth, of the horizontal cross section of the barrel

Answer 1

For the cross-section,
C = 2πr
A = πr^2

Now, what is this other area of 33.5 in?
area is in units of in^2
