Circumference of circle given radius
WebThe radius, diameter, and circumference of a circle are all related through the mathematical constant π, or pi, which is the ratio of a circle's circumference to its diameter. The value of π is approximately 3.14159. π is an irrational number meaning that it cannot be expressed exactly as a fraction (though it is often approximated as ) and ... WebGiven, Radius of the circle = 28 cm. To find the circumference of the circle, we will use the circumference formula: 2πr = 2 × 22/7 × 28 = 176 cm. Therefore, the circumference of the circle is 176 cms. Example 2: …
