For a given circle of radius 4 cm, the angle of its sector is 45°. Find the area (in cm2) of the sector. (Use π = 3.14.)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 6.28.
Area of the sector of the circle = (θ/360)πr2
According to the question;
⇒ (45/360) × 3.14 × 42
⇒ 6.28
