Infinitely big.
Except that, if the universe is closed and curves back on itself, then any "straight" line in it will also follow the curvature of the space-time and so will form a circle whose radius is the same as that of the universe.
In either case, seriously BIG.
The radius is the straight line distance from the centre of the circle to any point on the circumference of the circle. It can be measured in 'mm', or 'inches' or other units both metric and imperial .
-- Draw a circle. -- Put a mark at the center, and draw a line across the whole circle through the center. -- Measure the length of the curved line all around the circle. (called the "circumference" of the circle) -- Measure the length of the straight line across the circle. (called the "diameter" of the circle) If you divide the circumference by the diameter, the result is 'pi'. It doesn't matter how big or how small the circle is. The result is always the same.
be more specific
the big circle that covers the free throw line

Any number you like. You can have a tiny circle with a tiny diameter or a huge big circle with a big diameter. The diameter is simply the "width" of the circle. It is the length of the line from one side to the other which passes through the centre.
The diameter of a circle is a straight line passing through the center of the circle and connecting two points on the circumference. The length of the diameter is equal to twice the radius of the circle. If we assume the diameter is 1 unit, then it would be equivalent to 1 centimeter. Therefore, there are 1 centimeter in 1 diameter.
The center circle is 12 feet by 12 feet and is 38 feet away from the side line.
One of the most important functions of the radius is anchoring the muscles of the upper arm and the forearm. It is found on the thumb side of the forearm and rotates to allow the hand to pivot at the wrist.
The Circle Line Tours/Cruises are boat tours around the island of Manhattan (they go in a circle around the island). They are a big tourist attraction and have multiple tours daily. See the Related Link below for their official website.
In the middle. Its not always straight but she likes to make big curls for the show
Because it's a nice visual tool, and all the segments will add to a complete whole.To fill in a pie chart with percents (that all add up to 100%), here's what you do:(1) Identify the percent of the circle that you want to fill in. Say you want to color 45% of the circle red--that's a pretty big slice. Keep in mind that 45% in decimal form is 0.45 (I just moved the decimal over two places to the left).(2) Take that decimal, 0.45 in this case, and multipy it by 360, because there are 360 degrees in a complete circle. 0.45*360 = 162, so you will color 162 degrees of the 360 degree circle.(3) Use a protractor to draw a circle (one half at a time, probably) complete with an origin, the point in the very middle. Also draw one straight line (anywhere) from the origin to the edge of the circle.(4) Place the 0 degree line on your protractor over the line you just drew. Using the marks on your protractor, mark on the edge of your circle where 162 degrees is, in reference to the first straight line.(5) Remove your protractor and draw another straight line from the 162 degree mark you made on the edge of your circle to the origin. Between those two lines is 162 degrees, or 45% of a complete circle.This is process can be repeated for any percentage between 0 and 100.
