A sector has an area of 3m22 squared and subtends an angle of 80° at the centre of a circle.What is the radius of this circle?
Question
Solution 1
The formula for the area of a sector of a circle is given by:
Area = (θ/360) * π * r²
where: θ is the angle the sector subtends at the centre of the circle, r is the radius of the circle.
We can rearrange this formula to solve for r:
r = sqrt(Area / ((θ/360) * π))
