A sector of a circle having a radius of 10 cm and has a central angle of radians. What is the area of the sector?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 37.5π cm2.
Sector radius = 10 cm
Angle = 3π/4 radians
Area = (1/2)r2θ = 0.5 × 100 × 3π/4 = 37.5π cm2
