A sector has a central angle of 90° and a radius of 6 cm. Another sector has a central angle of radians. What is the ratio of the area of the first sector to the area of the second sector?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 1 : 1.
Sector 1: Central angle = 90°
Sector 2: Central angle = π/2 radians = 180°/2 = 90°
So, both sectors have the same angle and the same radius.
Area ratio = 1 : 1
