Answer 2

Answer:

Circumference of circle = 2πr, where r stands for radius and π = 22/7

Circumference = 22 cm = 2πr

Circumference = 22/2 = 22/7 × r

Circumference = 11 = 22/7 × r

Circumference = r ( radius ) = 7/2 cm

Area of circle = πr^2

Area = 22/7 × 7/2 × 7/2

Area = 77/2 sq.cm

Area = 38.5 sq.cm
