How to Find the Circumference of a Circle with Radius r = 8 cm?

The circumference of a circle is the perimeter of the circle. It is the total length of the boundary of the circle

Answer:  The Circumference of a Circle with Radius r = 8 cm is approximately equal to 50.29 cm

Circumference of a circle can be found using the formula, C = 2πr

Explanation:

Given, Radius of the circle, r = 8 cm

We know that,

Circumference, C = 2πr

= 2 × (22/7) × 8  {Using π = 22/7}

= 352/7

≈ 50.29 cm

Thus, the circumference of a circle with radius r = 8 cm is 50.29 cm
