Question

What is the area of sector whose arc lenght and radius are 22 cm and 7 cm respectively.

Answer 1

Arc length  (L) = 20 cm

                    r = 7 cm

     Area of sector = (1/2) lr  

                         =  (1/2) x 22 x 7

                         =  11 x 7

                         = 77 square units.

Answer 2

Answer:

77cm²

Step-by-step explanation:

Area of a sector = 1/2 * arc length * radius

∴ Area = 1/2 * 22 * 7 = 77cm²
