Then round to the nearest. Do not round until the final answer. Given that the radius of the circle.

Find the area of the sector. I when the central angle and the radius are given. Substitute 2 in for the radius.

Areaofasector frac Angle 360circ times pi. 12 22 68 pi 180 3445 so you have 34pi45. Area of sector θ 360 πr 2.

There are two methods to find the area of a sector. Area of a sector. Then to find the area of a sector divide 90 by the total degrees in a circle and multiply it by the area.

Up to 10 cash back A certain sector of the circle has a central angle of. Up to 10 cash back To solve first find area. Try keeping pi outside of the calculations so you get an exact answer.

But where does it come from. R 111 cmθ 69 The area is approximately cm2. The area of a circle pi r2.

The area of the sector is only a portion of. Calculate The Area Of A Sector Using Formula In Degrees We can calculate the area of the sector given the central angle and radius of circle.
