The line segment from the center of a circle to any point on the circle?
The line segment from the center of a circle to any point on the circle is called the radius. All radii in a given circle are equal in length, which is a defining characteristic of a circle. The radius plays a crucial role in determining the circle's area and circumference, with the area calculated as ( \pi r^2 ) and the circumference as ( 2\pi r ), where ( r ) is the length of the radius.
How do you write an equation in standard form of a circle with a center and radius?
The standard equation of a circle, with center in (a,b) and radius r, is: (x-a)2 + (y-b)2 = r2
What is radius of a circle?
Its the distance from the center of the circle to the edge of the circle.
What measures the distance from the center point of a circle to any point on the circle?
The distance from the center point of a circle to any point on the circle is measured by the radius. The radius is a constant length for a given circle and is typically denoted by the letter "r." It is half the diameter, which is the distance across the circle through its center.
If the radius of a circle is r what is the diameter of the circle?
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
What is the equation of a circle whose center is at the origin and whose radius is 10?
The equation of circle is (x−h)^2+(y−k)^2 = r^2, where h,k is the center of circle and r is the radius of circle. so, according to question center is origin and radius is 10, therefore, equation of circle is x^2 + y^2 = 100
How do you find the diameter of a sphere?
R (radius) X2. The radius is half the circle from the center of the circle. The diameter is just straight across.

What is r for the formula for the area of a circle?
Area of a circle = pi R2 'R' is the length of the radius of the circle. That's the distance from the center of the circle to any point on the circle.
How do you write an equation in standard form of a circle with a center and radius?
The standard equation of a circle, with center in (a,b) and radius r, is: (x-a)2 + (y-b)2 = r2
What is radius of a circle?
Its the distance from the center of the circle to the edge of the circle.
How do you find the area center radius diameter of a circle?
d/2=r
What measures the distance from the center point of a circle to any point on the circle?
The distance from the center point of a circle to any point on the circle is measured by the radius. The radius is a constant length for a given circle and is typically denoted by the letter "r." It is half the diameter, which is the distance across the circle through its center.
If the radius of a circle is r what is the diameter of the circle?
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
What is Pi R Squared?
The formula to get the area of a circle ("R" being the radius of the circle). Radius means the distance from the center of the circle to the edge.It means pi times radius squared which is the formula for finding the area of a circle.
What is equation of a circle whose center is at the origin?
x2 + y2 = r2, where r is the radius.
What is the relationship between the chord and the radius of circle?
The relationship between the chord and the radius of the circle is Length of the chord = 2r sin(c/2) where r = radius of the circle and c = angle subtended at the center by the chord
