What is difference between a radius and a diameter?
Radius is the shortest distance via straight line between the center point of the circle and its perimeter. Diameter is the greatest distance via straight line from one perimeter of the circle to the opposite perimeter. Diameter = 2x Radius.
What is 2 parts of a circle?
Parts of a circle include the diameter, circumference, radius, and center. The diameter of a circle is a chord passing through the center. The center is a single point at which the distance to locations on the circumference are equal. The circumference is the perimeter of the circle. The radius of the circle is half the diameter, and the distance from the center to a point on the outlying circumference.
What is the radius of the circle equal to?
Radius of a circle= Perimeter of the circle/2*pi Radius is half the diameter Radius is the length of a straight line from the center point of the circle to the edge of the circle.
If a circle has a radius of 7.5 feet what is it's diameter?
The radius is half the diameter (R = D/2). The radius goes from the center of the circle to a point along the perimeter, while the diameter goes across the entire circle, connecting two points opposite each other along the perimeter. If the radius is 7.5 feet, then the diameter is 13 feet.
What is the opposite point from the center of a circle?
The perimeter.
What is the diameter of a cup?
The diameter of a circle is the length of a straight line segment going from one point on the circle to a point on the opposite side, passing through the center point of the circle. The diameter of a cup would be the diameter of the circular face of the cup.
The diameter of a circle?
The diameter of a circle is a straight line going from one point on the circumference (the boundary) of the circle, through the centre of the circle, to another point on the circumference.
What is the mid point of a circle?
It is in the middle of its diameter which is the center of the circle
Diameter of a circle is 16cm what is the radius?
The diameter of a circle is the length of a straight line from a point on the edge of the circle passing through the center of the circle and onto a point on the opposite edge of the circle. The radius of a circle is the length of a straight line from the center of a circle to a point on the edge of the edge of the circle. So the radius of a circle is half its diameter, in this case 8cm.
What is diameter and radius?
the radius is a line from the middle of a circle to a point of the circle. the diameter is two times the radius.
Is the tangent of a circle its radius?
No, a tangent is a line that intersects a circle at exactly one point. The radius of a circle is the distance from the center of the circle to any point on the perimeter of the circle.
The diameter of a circle is 19 inches. If the diameter is extended 5 inches beyond the circle to point C, how long is the tangent segment from point C to the circle?
6.283 inches
