The area of the sector of a circle (in cm2) of radius 7 cm and central angle 60° is: (Take π = 227\frac{22}{7})

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 773\frac{77}{3}.

The radius of a circle (r) = 7 cm

The sector angle = 60º

The area of the sector of a circle = (θ/360°) × πr2

where r is the radius of the circle and 𝜃 is the angle of the sector.

Area = (θ/360°) × πr2 = (60/360) × (22/7) × 49 =77/3 cm2
