Q: A: ### Quick Answer

If the radius of the circle is known, the diameter formula is diameter=2R, where R equals the circle's radius. If the circumference of the circle is known, the diameter is found using diameter=C/Pi, where C is the circumference and pi is approximately 3.142.

Know MoreIf the area of a circle is known, the diameter is the square root of 4A/Pi, where A is the area of the circle and Pi is approximately 3.142. The diameter of the circle is the length of the line through the center of the circle that touches two of the points on its edge The center of the circle is the midpoint of the diameter. A diameter may also be referred to as a chord, which is any line that joins two points on a circle. The diameter is the longest chord on any circle.

## How do you find the domain and range of a circle?

A:The domain of a circle is the X coordinate of the center of the circle plus and minus the radius of the circle. The range of a circle is the Y coordinate of the center of the circle plus and minus the radius of the circle. It is easy to remember which coordinates domain and range refer to because X is alphabetically before Y, and domain is alphabetically before range.

## What is the standard turning radius for a vehicle?

A:The turning radius of a vehicle is the diameter of the narrowest circle it is capable of maneuvering and is dependent on many design factors, including wheelbase length, axle width, and the steering mechanism design. Midsized cars, depending on brand, normally have a turning radius of 34 to 38 feet.
