Consider the polar curve r is equal to 4 sine 2 theta What is the length of each petal, and how many petals does the graph have?

For a rose curve r = a sin(nθ), the maximum distance from the pole to the tip of a petal is |a|. Here, |a| = 4, so each petal has length 4. Because n = 2 is even, the graph has 2n = 4 petals. Thus, the correct choice is “The length of each petal is 4, and the number of petals is 4.”
