<-- Central Angle θ

A circle has a radius of 5 and a central angle in radians θ = 0.9. Calculate the arc length (s) and area of the sector (A)

Calculate arc length (s):
The formula for the arc length of a circle (s) is below
s = rθ where θ is in radians
s =5(0.9)

s =4.5π

s = π

Calculate sector area (A):
The formula for the area of a circle sector (A) is below
A =r2θ
2

where θ is in radians
A =52(0.9)
2

A =25(0.9)
2

A =22.5π
2

A = 11.25π
