A rose garden is formed by joining a rectangle and a semicircle, as shown below. The rectangle is 25 ft long and 20 ft wide. If the gardener wants to build a fence around the garden, how many feet of fence are required? (Use the value 3.14 for it,
and do not round your answer. Be sure to include the correct unit in your answer.)

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
