A sector of a circle has a central angle of 120° and a radius of 5 cm. Another sector of the same circle 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: A
Explanation
The correct answer is Option 1 i.e. 1:1.
120° = 120 × (π/180) = 2π/3 radian
Since both have the same radius and same angle, their areas are equal.
Required ratio = 1 : 1
