A sector of a circle has a central angle of 60° and a radius of 9 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.
First sector: Central angle = 60°
Second sector: Central angle = π/3 radians = 180°/3 = 60°
Since both sectors have the same angle and radius, the areas are equal.
Required ratio = 1 : 1
