A circle has the following:
Radius = 5
Central angle = θ = 0.9
Calculate the arc length and sector area
Calculate arc length (s):
s = rθ
where θ is in radians
Plug in r = 5 and θ = 0.9
| s = | 5(0.9) |
| s = | 4.5π |
s = INFπ
Calculate sector area (A):
| A = | r2θ |
| 2 |
where θ is in radians
Plug in r = 5 and θ = 0.9
| A = | 52(0.9) |
| 2 |
| A = | 25(0.9) |
| 2 |
| A = | 22.5π |
| 2 |
A = 11.25π
Final Answer
s = INFπ
A = 11.25
