Respuesta :
C = 2πr
r = 3
Input the variable:
C = 2π3
Multiply:
C = 6π
C = 6*3.14
C = 18.84
The circumference of the circle would be 18.84 inches.
As you know, we must use the formula C = 2πr.
So we just replace some parts.
C=2π3.
C=6π
18.84
There is also another way.
C = 2πr
To solve a circle, you must add both radius and make it into a diameter.
Then you multiply by π(pi)
Then you will get the answer / circumference.
