The circumference of a circle of radius r cm is 2*pi*r cm so the length of the semi-circular arc is pi*r cm.
The length of the diameter is 2*r cm so the total length is (pi + 2)*r cm

Work out the length of the coordinates and half it.
the radius is half the diameter. radius is half of 11. Which is 5.5.
The radius is half the diameter.
The length of a radius of a circle is half of the diameter of the same circle. So, diameter is always twice the radius.
The diameter is the length of a line touching both sides of the circle and passing through the centre. The radius is the length of a line from the centre to touching the circle, and is half the length of the diameter, the diameter then is twice the length of the radius > diameter = radius * 2 = 32 * 2 = 64
