A sector of a circle has a central angle of 60° and a radius of 8 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: C
Explanation
The correct answer is option 3 i.e. 1:1.
Sector 1: Central angle = 60° = π/3 radians
Sector 2: central angle = π/3 radians
Radii of two sectors are the same = 8 cm
The areas of the two sectors are also the same.
Ratio of the area of the first sector to the area of the second sector = 1 : 1
