Draw the pentagon on the outside of the circle with all five sides touching the circle. Now by dividing the pentagon into 5 equal segments to the center, the circle is divided as well into 5 equal segments. Mathmatically speaking, see the related link for more information

What number of degrees is in a circle?
A circle has 360 degrees
How many degrees is 16 of a circle?
Every circle by definition has 360 degrees. If it did not have 360 degrees, it would not be a circle. Therefore, 16 degrees of a circle is 16o over 360o.
What is 90 degrees of a circle?
The circumference of a circle is 360 degrees. 1/4 of 360 is 90. So 90 degrees is a quarter of a circle. It is called a quadrant.
How many degrees is one tenth of a full circle?
One tenth of a full circle is 36 degrees.
How do you divide circle in 8 equals parts?
You divide 360 degrees by eight (there are 360 degrees in a circle) so each section would be 45 degrees.
What shape will stay the same no matter how many degrees it is rotated?
a square,circle,pentagon
Angle of 540 degrees?
There is no such thing as an angle with 540 degrees. It only goes up to 360 where it is a perfect circle. However a pentagon has a total of 540 degrees.
When constructing a circle what part of the of the circle is drawn by the compass?
Perimeter
A regular pentagon is inscribed inside a circle that has radius of length 9 What is the measure of each angle in the pentagon?
Since it is a regular pentagon, all the sides are the same length. Hence the pentagonal centre is the same as the circle centre. This makes for 5 Isosceles triangles, that construct the pentagon. Taking the centre divide the centre angle of 360 degrees by '5' . Hence 360/5 = 72 degrees for each pentagonal Isosceles triangle. Using the Isoscelean Law the other two angles are (180 - 72) / 2 = 54 degrees. Hence the internal angles of the pentagon are each 108 degrees. Hope that helps!!!!!

What is the perimeter of a pentagon in an insribe circle if the pentagon has n-sided and the redius of a circle is r?
the perimeter of a pentagon 30 that is the perimeter because the pentagon has 5 sides and the measurement of each side measures to 6 inches so you multiply 5x2=30
