[b]uArc length[/u]/b
The formula for arc length ((l)) is:
(l=rθ)
where (r) is the radius, and
(θ) is the angle in radians.
[b]uArea of a sector[/u]/b
The formula for area of a sector ((A)) is:
(A=\dfrac{1}{2}r2θ)
where (r) is the radius, and
(θ) is the angle in radians.
[b]uArc length[/u]/b
(l=rθ)
where (r) is the radius and (θ) is the angle in radians.
[b]uArea of a sector[/u]/b
(A=\dfrac{1}{2}r2θ)
where (r) is the radius and (θ) is the angle in radians.
