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

How can you find the radius of a circle with coordinates?
Work out the length of the coordinates and half it.
If the length of a diameter of a circle is 11 what is the length of a radius of this circle?
the radius is half the diameter. radius is half of 11. Which is 5.5.
What is the relationship between the length of a radius of a circle and the length of a diameter of the same circle?
The radius is half the diameter.
How do you find the diameter if the radius for a circle is 32?
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
What is the length of a radius and the length of a 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.
How can you find the radius of a circle with coordinates?
Work out the length of the coordinates and half it.
How do you find the length of the chord of a circle?
There are a couple of different ways of finding the length of the chord of a circle. Probably the best is what is called the half angle formula.
Where can you find the radius?
Radius is half the length from one side of a circle to the other or half the diameter.
If the length of a diameter of a circle is 11 what is the length of a radius of this circle?
the radius is half the diameter. radius is half of 11. Which is 5.5.
How do you find the radius given the chord length?
If you are given a chord length of a circle, unless you are given more information about the chord, you can not determine what the radius of the circle will be. This is because the chord length in a circle can vary from a length of (essentially) 0, up to a length of double the radius (the diameter). The best you can say about the radius if given the chord length, is that the length of the radius is at least as long has half half the chord length.
What is the relationship between the length of a radius of a circle and the length of a diameter of the same circle?
The radius is half the diameter.
If the diameter of a circle is 4 centimeters what is the length of the radius?
Length of a radius is always half the diameter of a circle. This means that the circle has a radius of 2cm.
What is the relationship of a radius and a diameter of a circle?
the radius is half the length of the diameter of a circle.
How do you find the diameter of a circle with the width and length?
The width, or the length of a circle are its diameter.
What is the length of a radius and the length of a 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.
How do you find the diameter if the radius for a circle is 32?
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
What is the circonference of a circle?
the circumference of a circle is half of the length between 2 edges of the circle times 3.14.
