This means if you went a distance of 2 away from that center point you would be on the circle.

WebThus, the area of a segment of a circle is obtained by subtracting the area of the triangle from the area of the sector. i.e., Area of a segment of circle = area of the sector - area … WebJun 18, 2024 · The formula is very simple: A = pi * r^2 which means the area is Pi (3.14159...) times the square of the radius. In a book it would look more like this: __ 2 A = r To use this formula, just measure the radius of the circle (which is half the diameter), square it (multiply it by itself), and then multiply the result by 3.14.

WebRemark: This is a very time consuming way to find the area of a sector with angle $\theta$. For the area of the sector, if $\theta$ is given in radians, is$\dfrac{\theta}{2\pi}$ times the area of the circle. That gives area $\dfrac{\theta}{2}r^2$.
