In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

r = 7 sin (2θ)

Step 02:

polar equation:

r = 7 sin (2θ):

r = a sin nθ

n odd ==> n petals

n even ===> 2n petals

n = 2 ===> 2*2 petals = 4 petals

graph:

length of the petals:

r = 7 sin (2θ)

θ = 45°

r = 7 sin (2*45°) = 4.95

The answer is:

4.95
