Using integration, find the area of the region enclosed between the circle x^2+y^2=16 and the lines x=-2 and x=2.
Using integration, find the area of the region enclosed between the circle $\displaystyle x^{2}+y^{2}=16$ and the lines $\displaystyle x=-2$ and $\displaystyle x=2$.
Marking-scheme solution
Required area $\displaystyle =4\int_{0}^{2}\sqrt{16-x^{2}}\,dx$$\displaystyle =4\left[\dfrac{x}{2}\sqrt{16-x^{2}}+8\sin^{-1}\left(\dfrac{x}{4}\right)\right]_{0}^{2}$$\displaystyle =8\sqrt{3}+\dfrac{16\pi}{3}$All Application of Integrals questions2024 question paperNCERT solutions: Application of IntegralsPractice Application of Integrals →
