# Find the Circumference circle (17.5)

r=17.5
The circumference of a circle is equal to Pi π times the diameter d.
π⋅(diameter)
Since the diameter d is equal to 2 times the radius r, the formula for circumference using radius is 2πr.
Substitute the value of the radius r=17.5 into the formula for the area of a circle. Pi π is approximately equal to 3.14.
2⋅π⋅17.5
Multiply 2π⋅17.5.
Multiply 17.5 by 2.
35π
Multiply 35 by π.
