Problem #2
Crops are often grown using a technique called center pivot irrigation
that results in circular shaped fields. The length of the irrigation pipe is
the radius of the rotation.
Part 1: The irrigation pipe is 450 meters in length and the sprinkler system rotates 125
degrees.
a) Draw and label a diagram for the situation.
b) What is the degree of rotation in radians?
c) What is the distance the tip of the sprinkler travels to the tot he nearest inch?
Part 2: An area of 300,000 square meters has been irrigated after a rotation of
a) Draw and label a diagram for the situation.
b) What is the degree of rotation in degrees?
c) What is the length of the irrigation pipe?
