Is the distance from the center of a circle to a point on the circle?

The distance from a circle’s center to a point on the circle is called the radius of the circle. A radius is a line segment with one endpoint at the center of the circle and the other endpoint on the circle.

What is the relationship between the centre of the circle and the radius?

Circle Relationships You can measure the distance from the center of the circle to the outer edge. This distance is called the radius. Notice that the radius is one-half of the measure of the diameter. You can measure the perimeter of the circle too.

How is the distance formula related to the equation of a circle?

Use the Distance Formula to find the equation of the circle. Substitute (x1,y1)=(h,k),(x2,y2)=(x,y) and d=r . Square each side. The equation of a circle with center (h,k) and radius r units is (x−h)2+(y−k)2=r2 .

What is the distance from the center to the edge of a circle?

radius
The radius of a circle is the distance from the center of the circle to the outside edge. The diameter of a circle is longest distance across a circle.

What is the distance of the Centre of a circle from any point on the circle if the radius of the circle is 10cm?

So the distance of the chord from the center is 8 cm.

What is the relationship between diameter and radius of circle?

Radius = diameter÷2.

Which equation shows the correct relationship between the radius and the diameter of a circle?

Radius = Diameter2. For Example: 1. Find the diameter of a circle whose radius is 4.5 cm.

What is the distance across the center of a circle called?

diameter
The distance across a circle through the centre is called the diameter. The distance from the centre of a circle to any point on the boundary is called the radius. The radius is half of the diameter; 2r=d 2 r = d . The line segment that joins two points on the circle is a chord.
