The calculated area inside one leaf of the rose: r=6sin(5θ) is 2.24
How to determine the area inside on leaf of the rose
From the question, we have the following parameters that can be used in our computation:
We have:
r = 6sin(6θ)
First we have to find the limits:
r = 0
6sin(6θ) = 0
θ = nπ/6
n = 0 to n = 1
θ = 0 to θ = π/6
So, we have

Integrate and evaluate
Area = 2.24
Hence, the area inside one leaf of the rose: r = 6sin(5θ) is 2.24
