Circumference = 8.8 cm
=> 2 *pi *r = 8.8
=> 2*22*r/7 = 8.8
=> r = 8.8 * 7 / 44
=> r = 0.2 * 7
=> r = 1.4 cm
Diameter = 2.8 cm
=> 2 *pi *r = 8.8
=> 2*22*r/7 = 8.8
=> r = 8.8 * 7 / 44
=> r = 0.2 * 7
=> r = 1.4 cm
Diameter = 2.8 cm

Circumference of circle = 2*pi*r
8.8 cm = 2*22/7*r
r = 8.8*7/2*22
r = 1.4 cm
d = 2*r
= 2*1.4
= 2.8 cm
8.8 cm = 2*22/7*r
r = 8.8*7/2*22
r = 1.4 cm
d = 2*r
= 2*1.4
= 2.8 cm
