Question

The area of the large sector if radius is 7cm and pie is 22over7 angle 120 degrees.

Answer 1

51.33 cm^2

Explanation:

Radius = 7 cm.

theta = 120 deg.

Area of sector = theta/360 × pi × r^2.

= 120/360 × 22/7 × 7 × 7.

= 1/3 × 22 × 7

= 154/3 cm^2.

= 51.33 cm^2.

Hence the area is 154/3 or 51.33 cm^2.
