The area of circle PQR with centre o is72cm2. What is the area of sector POQ if angle POQ =40 degree ?
Solve without explanation
30.01 cm² (rounded to two decimal places)
To find the area of sector POQ, you can use the formula:
Area of sector = (Angle/360) * π * r^2
Given:
Area of circle PQR = 72 cm^2
Angle POQ = 40 degrees
Let's assume the radius of circle PQR is 'r'.
Using the given information, the area of sector POQ can be calculated as follows:
Area of sector POQ = (40/360) * π * r^2
Let me calculate that for you.
