Answer:

C = 11 then d= 3.5

C =66 then d = 21.01

C = 74 then d = 23.55

C =132 then d = 42.02

Answer:

1.i.let the radius be r

Therefore,

2πr=Circumference

=>2×(22/7)×r=11

=>r=(11×7)/(22×2)

=>r=1.75 cm

diameter=1.75×2

=3.5cm

2.i. Diameter=14cm

Radius=14/2

=7cm

Area=πr²

=(22/7)×7×7

=154cm²

Rest do by yourself...

Hope it is clear...
