Examples on Circumference of Circle
Some examples on Circumference of a circle are,
Example 1: What is the circumference of a circle with a diameter of 2 cm?
Solution:
Given,
- Diameter = 2 cm
By using formula of circumference of a circle,
C = π × d
C = 3.14 × 2
C = 6.28 cm
Example 2: What is the circumference of a circle with a radius of 3 cm?
Solution:
Given,
- Radius = 3 cm
C = 2 × π × r
C = 2 × 3.14 × 3
C = 18.84 cm
Example 3: What is the circumference of a circle with a diameter of 14cm?
Solution:
Given,
- Diameter = 14 cm
C = π × d
C = 3.14 × 14
C = 43.96 cm.
Example 4: What is the circumference of a circle with a radius of 10 cm?
Solution:
Given,
- Radius = 10 cm
C = π × 2r
C = 3.14 × 2(10)
C = 62.8 cm.
