How do you find the circumference of a circle with the radius?
A circle is a closed curve where all points are at the same distance from the center.
Answer: The circumference of a circle can be found by 2πr, where r is the radius of the circle.
The circumference of a circle is its boundary or the length of the complete one of a circle.
Explanation:
We can calculate the circumference of a circle is by using the formula 2πr, where r is the radius of the circle.
For example: If r = 7cm then the circumference of a circle = 2πr = 2 × (22/7) × 7 = 44cm, where π = 3.14 or 22/7 approx.
Thus, the circumference of a circle is 2πr.
