Question

If the length of the wire is 11 cm, 22 CM, 33 CM then find the circumference of the circle, diameter of the circle and its ratio

Answer 1

The circumference of the circle, diameter of the circle and its ratio :

Given that the length of the wire is 11 cm, 22 cm, 33 cm.

• Circumference = Length of the wire

• Circumference of Circle1 = 11 cm

2×pi×r1 = 11 cm

r1 = 7/4

• d1= 7/2 cm

• Circumference of Circle2 = 22 cm

2×pi×r3 = 22 cm

r2 = 7/2

• d2 = 7 cm

• Circumference of Circle3 = 33 cm

2×pi×r3 = 33 cm

r3 = 7×3/4

• d3 =7×3/2

• Ratio,

d1 : d2 : d3 = 7/2 : 7 : 7×3/2

= 1 : 2 : 3
