<span>y=-3cos(2pi/5 x)
y=a cos (bx+c) +d
a=-3; b=2pi/5; c=0; and d=0
Period: P=2pi/b
P=2pi/(2pi/5)
P=2pi*[5/(2pi)]
P=(2pi*5)/(2pi)
P=5

Answer:
56.52 feet.
Step-by-step explanation:
We have been given that a rotating sprinkler sprays at a steady stream of water that is nine feet long. We are asked to find the approximate circumference of a circular area it sprays with water.
We will use circumference of circle formula to solve our given problem.
, where r represents radius of the circle.
Therefore, the circumference of the circular area is approximately 56.52 feet.
The answer to your problem is eleven <span />
