Sep 05, 2019 · To calculate the area of a sector, start by finding the central angle of the sector and dividing it by 360. Next, take the radius, or length of one of the lines, square it, and multiply it by 3.14. Then, multiply the two numbers to get the area of the sector. To find the shaded area of a circle, calculate the area of the full circle and multiply it by the fraction of the circle that is shaded. The fraction of the circle that is shaded can be determined by dividing the angle that the shaded region covers by 360 degrees. Apr 10, 2017 · How To Find The Area Of A Sector Of A Circle If the arc subtends an angle of θ at the centre, then its arc length is Hence, the arc length ‘l’ of a sector of angle θ in a circle of radius r is given by If the arc subtends an angle θ, then […]

Hi guys, another maths question. I am having trouble finding the method to do this, online and in my head. The question is: A sector with radius 6cm has an area 70cm sq. Calculate the angle of the sector Theta. This arc length calculator is a tool that can calculate the length of an arc and the area of a circle sector. In this article, we explain the arc length formula in detail and provide you with a step-by-step instruction of how to find the arc length. You will also learn the equation for sector area.
