An irrigation system waters in circular patterns. Each irrigated section is a circle with a diameter of 40 feet. In terms of π, what is the area of an irrigated section?
Area= pi*r^2 So since the radius is half of the diameter, you need to divide 40/2=20 radius = 20 pi*20^2 20^2=400 pi= 3.1415... pi*400=1256.63706... So area will equal =1256.63706..., (since pi is never ending) { I might be wrong.]
