Question

What is the area of sector ghp

Answer 1

Explanation:

Hello! Remember you have to write complete questions in order to get good and exact answers. Here you haven't provided any sector, so I'll help you in a general way and providing my own example.

A sector is a region of a circle between two radii. Suppose you have a central angle $\theta$ degrees, the sector can be found as:

$s=\frac{\theta}{360}\times\pi r^{2}$

Suppose that the radius of the circle is $4cm$ and the central angle is 90 degrees, therefor the sector is:

$s=\frac{\theta}{360}\times\pi r^{2} \\ \\ s=\frac{90}{360}\times\pi (4)^{2} \\ \\ s=\frac{1}{4}\times 16\pi \\ \\ \boxed{s=4\pi cm^2}$
