Question

if theta is angle of a sector of circle of Radius r area of sector is​

Answer 1

Answer:

If the angle at the center is θ in radians, the area of the sector is, area of a sector of circle = (1/2) × r2θ, where, θ is the angle subtended at the center, given in radians. r is the radius of the circle.

Answer 2

Answer:

If the angle at the center is θ in radians, the area of the sector is, area of a sector of circle = (1/2) × r2θ, where, θ is the angle subtended at the center, given in radians. r is the radius of the circle.
