Answer:

(i) Circumference of circle = 132 cm

2πr = 132

2 x 22/7 x r = 132

r = (132 x 7)/(2 x 22)

r = 21cm

∴ Area of circle = πr2

= 22/7 x 21 x 21

= 1386 cm2

(ii) Circumference of circle = 22 m

∴ 2πr = 22

2 x 22/7 x r = 22

r = (22 x 7)/(2 x 22)

r = 7/2

r = 3.5 m

Area of circle = πr2

= 22/7 x 3.5 x 3.5

= 38.5 m2
