What is the radius of the diameter?
Find the diameter or radius
The diameter is twice the radius, so the equation for the circumference of a circle with a radius is twice as many times the radius.
Is the radius equal to half the diameter?
Half the diameter or distance between the center and the edge of a circle is called the radius of the circle (r).
Is the diameter of the radius divisible by 2?
The radius of a circle or sphere is equal to the diameter divided by 2.
What is the radius of diameter 7?
The diameter is equal to twice the radius, or 2r. The radius of this circle is 7 inches, so the diameter is 2 (7) = 14 inches.
What is the diameter of spoke 4?
For example, if the circumference is 12.56, divide 12.56 by 3.14159 to get 4, which is the diameter of the circle. Use the diameter to find the radius by dividing the diameter by 2. For example, if the diameter is 4, the radius will be 2.
What is the radius of the semicircle?
The circumference of a semicircle is equal to the sum of half the circumference and the diameter. Because the circumference is 2πr or πd. Therefore, the circumference of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius.

What are the radius and diameter of the circle?
The radius is the distance from the center to the outside. The diameter passes directly through the circle, through the center. The perimeter is the distance along a circle.
Is R 2 equal to the diameter?
2 and r are derived from the diameter formula. You need to find the circumference of the circle. Pi comes here for his relationship. 2, and r comes because it is equal to the diameter.
What is the relationship between radius and diameter?
The radius is the distance between the center of a circle and any point on its circumference. The diameter of a circle is a straight line through the center whose endpoints meet on the circle. So the radius is half the diameter.
How to calculate the diameter?
The radius is the length from the center of the circle to the edge. So if you know the radius, multiply it by two to find the diameter (diameter = 2 x radius).
What is meant by radius and diameter?
Definitions The radius of a circle is the distance connecting the center of the circle to any point on the circle. A circular chord is a line segment that connects any two points on the circle. The chord of a circle that passes through the center of the circle is called the diameter of the circle.
