Final answer:
The area of the region enclosed by the curve r = 7cos(3θ) is 49 times the square of the cosine of 3θ.
Step-by-step explanation:
The area of the region enclosed by one loop of the curve r = 7cos(3θ) can be found using the formula A = r².
Substituting the given value of r = 7cos(3θ), we have A = (7cos(3θ))².
Simplifying, A = 49cos²(3θ).
The area of the region enclosed by one loop of the curve is 49 times the square of the cosine of 3θ.
