If the distance from the centre of the pentagon to a vertex is r cm then the length of the arc is 0.4*pi*r cm
The circumference of a circle measures the distance around the circle.
The equation for the circumference of a circle is pi times radius squared.
Circumference=πd thefore it is 44
The circumference is the distance around a circle and it is measured by:- Circumference of a circle = 2*pi*radius or pi*diameter

The measure of an arc is part of the circumference of a circle
Measure the distance from the centre of the circle to its circumference.
You measure it. If you know the radius (of a circle), you multiply it by 2 to get the diameter. If you know the circumference of a circle, you divide by pi to get the diameter.You measure it.

Circumference of a circle = 2*pi*radius
assuming this is a regular pentagon (all five sides are equal length) the center is the intersection of the intersection of perpendicular bisectors of each side and should also be the center of the circle in which it is inscribed
