Question:

Find the area of the portion of the circle $x^2+y^2=64$ which is exterior to the parabola $y^2 =12x$.

Options:

$\frac{16}{3}(8π-\sqrt{3})$

$\frac{4}{3}(8π-\sqrt{3})$

$\frac{5}{3}(8π-\sqrt{3})$

$\frac{2}{3}(8π-\sqrt{3})$

Correct Answer:

$\frac{16}{3}(8π-\sqrt{3})$

Explanation:

Required Area = $π8^2-2\int\limits_0^A[\sqrt{64-y^2}-\frac{y^2}{12}]dy$

$⇒\frac{16}{3}(8π-\sqrt{3})$
