Answer:so to find the circumference of a circle, you need an equation
C=2πr
When you used this equation you do 2 x 3.14 x radius
Radius of the circle is usually given but if you aren’t given the radius in the problem you can’t solve
Step-by-step explanation: hope this helps :)
The circumference of a circle is the amount of space that surrounds the circle
To calculate the circumference of a circle, we make use of the following formula
C = 2πr
Where r is the radius of the circle, and π = 3.14
Assume the radius is:
r = 5,
The circumference becomes
C = 2 * 3.14 * 5
Evaluate
C = 31.4
Hence, the circumference of a circle that has a radius of 5 units is 31.4 units
