From a circle with a radius of 15.75 cm, a sector with an arc length of 11 cm is cut off. Find the area (in cm2 ) of this sector.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 86.625.
The formula to find the area of a sector = (r × l)/2
where, r = radius, and l = length of the arc
Now,
Area of the sector = (15.75 × 11)/2 = 86.625 cm2
