A sector with an area of 140 pie cm^2 has a radius of 20 cm. r = 20 cm
A = 140 pie cm^2
What is the central angle measure of the sector in degrees?

Central angle = 126°

Step-by-step explanation:

Area of the sector = 140π cm²

Radius of the given circle = 20 cm

Since area of the sector =

[where θ is the central angle formed by the sector at the center]

                               140π =

                                    θ =

                                    θ = 126°

Therefore, central angle of the sector will be 126°.
