How do you find the centre of a circle given part of a radius?
Golfpin
You would have to know the length of the radius. The center of the circle is at one end of the radius. If you just know where some part of the radius is, and not that the part touches the circle then you cannot know where the center is without at lest a point on the circumference.

How do you find the radious of a circle can you find the circumference?
The radius of a circle is the distance from its centre to its circumference. If a circle has a radius of r units then the length of its circumference is 2*pi*r units.
How do you find distance if radius is given?
Diameter of a circle = 2*radius Circumference of a circle = 2*radius*pi
When given the radius of a circle how do you find the diameter?
You times the radius by 2.
How do you find radius of a circle if cord length is given?
The longest chord in a circle is its diameter and halve of this is its radius.
How do you find the diameter if the radius for a circle is 32?
The diameter is the length of a line touching both sides of the circle and passing through the centre. The radius is the length of a line from the centre to touching the circle, and is half the length of the diameter, the diameter then is twice the length of the radius > diameter = radius * 2 = 32 * 2 = 64
How do you find the area of a circle without knowing the radius?
If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.
How do you find radius of circle?
Measure the distance from the centre of the circle to its circumference.
How do you find the radious of a circle?
The radius of a circle is any straight line from the centre of the circle to its circumference. The radius can also refer to the length of this line.
How do you find the diameter of a circle given the radius?
Double the radius
Where can you find the radius?
Radius is half the length from one side of a circle to the other or half the diameter.
How do you find the radious of a circle can you find the circumference?
The radius of a circle is the distance from its centre to its circumference. If a circle has a radius of r units then the length of its circumference is 2*pi*r units.
How do you find distance if radius is given?
Diameter of a circle = 2*radius Circumference of a circle = 2*radius*pi
How do you find out if each point is on inside or outside of the circle?
Find the distance of the point from the centre of the circle. If the distance is - less than that radius then the point is inside the circle, - equal to the radius then the point is on the circle, and - greater than that radius then the point is outside the circle.
When given the radius of a circle how do you find the diameter?
You times the radius by 2.
How do you find radius of a circle if cord length is given?
The longest chord in a circle is its diameter and halve of this is its radius.
How do you find the diameter if the radius for a circle is 32?
The diameter is the length of a line touching both sides of the circle and passing through the centre. The radius is the length of a line from the centre to touching the circle, and is half the length of the diameter, the diameter then is twice the length of the radius > diameter = radius * 2 = 32 * 2 = 64
How to get the formula to find radius in spherometer?
Treat the 3D sphere as a 2D circle. The radius for the sphere is the same radius as for the circle. No matter where on the sphere you place a mark, the distance (radius) from the mark to the centre of the sphere will always be the same as the circle.
