Circumference of circle = 132 cm
=> 2 pi r = 132
=> 2*22*r/7 = 132
=> 44r/ 7 = 132
=> r = 132 × 7 / 44
=> r = 3 ×7
=> Radius = 21 cm
Area = pi r^2
= 22 × 21× 21 / 7
= 22 × 63
= 1386 cm^2
=> 2 pi r = 132
=> 2*22*r/7 = 132
=> 44r/ 7 = 132
=> r = 132 × 7 / 44
=> r = 3 ×7
=> Radius = 21 cm
Area = pi r^2
= 22 × 21× 21 / 7
= 22 × 63
= 1386 cm^2
