Find the Circumference circle (3.5)

Math
r=3.5
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.
2π⋅(radius)
Substitute the value of the radius r=3.5 into the formula for the area of a circle. Pi π is approximately equal to 3.14.
2⋅π⋅3.5
Multiply 2π⋅3.5.
