Question 25
Mensuration of Plane ShapesA sector of a circle of radius 7cm has an area of 44cm2. Calculate the angle of the sector, correct to the nearest degree. (Take π = 22/7)
- A.6°
- B.26°
- C.52°
- D.103°
- E.206°
Show the answer and explanation
Answer: D (103°)
Explanation
θ/360 × 22/7 × 72 = 44 gives θ/360 × 154 = 44, so θ = 102.9° ≈ 103°.
