# What is the difference between radius and diameter?

• January 11, 2023 в 02:45

The radius of a circle is the length of a line extending from the center of the circle to any point on the circle's circumference. The diameter of a circle is the length of a line extending from one point on the circle's circumference to the opposite point on the circumference, passing through the center of the circle.

The difference between radius and diameter is that the radius is half the length of the diameter, so the diameter is twice the length of the radius. This is because the radius is the distance from the center of the circle to any point on the circumference, while the diameter is the distance from one point on the circumference to the opposite point on the circumference.

The radius and diameter are related in that the diameter is equal to twice the radius, so if the radius of a circle is known, the diameter can be calculated by multiplying the radius by two. Conversely, if the diameter of a circle is known, the radius can be calculated by dividing the diameter by two.
