The graph of a limacon curve is given. without using your graphing calculator, determine which equation is correct for the graph. a circular graph with an inner loop on the bottom [-5, 5] by [-5, 5] r = 2 + 2 sin θ r = 3 + sin θ r = 1 + 3 cos θ r = 1 + 3 sin θ

The only equation that can produce a loop at the bottom is the one that has opposite sign non-zero values for r at π/2 and 3π/2. The last selection meets that requirement.

r = 1 + 3 sin(θ)

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.

step-by-step explanation:

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50
