Explanation:

The formula to calculate the circumference (C) of a circle is C = 2πr, where r represents the radius of the circle.

In this case, the given circumference is 68 cm. Plugging this value into the formula, we can solve for the radius (r):

68 = 2πr

To find the radius, we can divide both sides of the equation by 2π:

r = 68 / (2π)

Using an approximate value of π ≈ 3.14159, we can calculate the radius:

r ≈ 68 / (2 × 3.14159) ≈ 10.8419 cm

Therefore, the radius of the circle, which has a circumference of 68 cm, is approximately 10.8419 cm.

GiveN:-

  • Circumference of Circle = 68 cm

To finD:-

  • Radius of Circle = ??

SolutioN:-

  • Circumference = 2 π r
  • 68 = 2 π r
  • 68 = 2 × (22/7) × r
  • 68 = (2 × 22/7) × r
  • 68 = (44/7) × r
  • (44/7) × r = 68
  • 44 × r = 68 × 7
  • 44 × r = 476
  • r = 476/44
  • ➝ r = 10.8 cm

Therefore, The Radius of the Circle is 10.8 cm.
