How to Create a 2.5 in. Diameter Circle Inside a 4.0 in. Diameter Circle

Explanation:

To make a 2.5 in. diameter circle inside a 4.0 in. diameter circle, you would use the offset command with an offset distance that is equal to the difference in radii of the two circles. The radius of the larger circle is half of 4.0 in., which is 2.0 in., and the radius of the smaller circle is half of 2.5 in., which is 1.25 in. To find the offset distance, subtract the radius of the smaller circle from the radius of the larger circle:

Offset distance = Radius of larger circle - Radius of smaller circle

Offset distance = 2.0 in. - 1.25 in. = 0.75 in.

Therefore, the offset distance you would use is 0.75 inches.
