If the circle radius is 27yd, how do I find the circumference without using pi?
lions [1.4K]

Circumference of a circle having radius of 27 yard can be found using the formula, π = 2(Area of Circle)/r, which is C = 169.6 yd

<h3>What is the Circumference of a Circle?</h3>
  • Circumference of a circle is the distance round the circle.
  • Circumference = Perimeter
  • Circumference of a circle without using π = 2(Area of Circle)/r.

Given:

radius of circle = 27 yd

Thus:

Area = πr² = π(27)²

Area = 2,290.2 yd²

Circumference of a circle without using π = 2(2,290.2)/27

= 169.6 yd.
