What is it when the point that is the same distance from all the points of a circle?
Your question implies that it could be the radius, diameter or even the chord of a circle in which the diameter is the largest chord of a circle.
What kind of unit does a circle have?
A circle can have a unit of length which could be either a measure of its diameter or radius, or of its circumference. Or the circle could have the unit of area.
Formula of circumference?
Formula of Circumference of a circle: 3.14*Diameter of the circle. You could also do: 3.14*3.14*radius.
What is the circumference of a circular table with a diameter of 15 inches?
Circumference is found by the equation C = 2 * pi * r, where r is the radius and pi is the constant pi. We are given the diameter. If you look at a circle, the diameter of it is the distance from one end of the circle to the other. We want the radius of the circle. The radius is the distance from any point along the circle to the center of the circle. If we let the diameter = d and the radius = r, we can write a formula for the diameter in terms of the radius. Because the radius is half of the distance of the diameter, d = 2*r 15 = 2 * r (divide both sides by 2) r = 7.5 so C = 2*7.5*pi C = 15pi Note that we could have used C = pi*d, although this is not usually how circumference is expressed.
What is the circumference of a circle with a radius of 4 inches?
The formula for finding the circumference is the diameter times pi because the radius is half of the diameter, the diameter of this circle would be 8 8 times pi equals approximately 25.1327 Or you could leave it in terms of pi and say 8pi (using the symbol)
Could you explain the radius of a circle?
The radius of a circle is the distance from the center of the circle to the outer edge Also known as half of the diameter. The diameter is the distance from opposite edges of the circle going through the centre.

Formula of circumference?
Formula of Circumference of a circle: 3.14*Diameter of the circle. You could also do: 3.14*3.14*radius.
How do you find and use the circumference of a circle?
The circumference of a circle is the distance around the outside of the circle. It could be called the perimeter of the circle. The circumference of a circle can be found by multiplying pi ( n = 3.14 ) by the diameter of the circle. If a circle has a diameter of 4, its circumference is 3.14*4=12.56. If You know the radius, the diameter is twice as large.

What is the exact area of a circle whos diameter is 6 cm?
There is no way to find the exact area of a circle. The formula for the area is Pi times the radius squared. But Pi is an irrational number -- that is, no matter how many numbers you write it out to, you could always write it further. Since there is no exact value of Pi there can be no exact value of the area based on the diameter. The radius is half that of a diameter. Therefore, if you know the diameter you know the radius. In this case the radius is 3cm and the area of the circle = pi * 32 So the answer is roughly
What is the perimeter of a circle with the radius of 7cm and diameter of 14cm?
The perimeter of a circle is equal to pi times the diameter, so for a circle with a diameter of 14 cm, multiply by pi, which is approximately 3.14, and you get 43.96 cm, which for most purposes you could round off to 44 cm.
How do you draw and label the diameter and radius on a circle?
The diameter is a straight line from one side of the circle to the other which passes through the centre of the circle. The radius is a straight line from the centre to the boundary of the circle. To label them, you could either write the words alongside the lines or, if the circle is too small, draw arrows from the two lines to outside the circle and write the words at the end of the arrow.
If you draw a circle with a radius of 29 centimeters what is it's diameter?
You take the radius of 29 centimeters and double it for the diameter - 58 centimeters.Then you could multiply the diameter of 58 centimeters by pi, which is 3.141 (approximately).This would give you the circumference of 182.178 centimeters.
How to calculate how big of circle could be made with length of a line?
IF YOU HAVE A LINE THAT WILL GO AROUND THE CIRCLE, DIVIDING BY PI (3.14159) WILL GIVE YOU THE DIAMETER. HALF THE DIAMETER IS THE RADIUS. IF YOU HAVE A LINE FOR DIAMETER, MULTIPLY BY PI TO GIVE THE CIRCUMFERENCE. TO DRAW THE CIRCLE, FOLD THE LINE IN HALF AND HOLD AT THE FOLD. EITHER OR BOTH OF THE ENDS WILL SWING AROUND THE CIRCLE. IF YOU USE YOUR LINE FOR THE RADIUS, MULTIPLY THE LENGTH BY 2, THEN MULTIPLY THAT RESULT BY PI. RADIUS IS 1/2 THE DIAMETER (1/2 THE DISTANCE ACROSS) DIAMETER IS THE DISTANCE ACROSS CIRCUMFERENCE IS ALL THE WAY AROUND IF YOU HAVE A LINE THAT WILL GO AROUND THE CIRCLE, DIVIDING BY PI (3.14159) WILL GIVE YOU THE DIAMETER. HALF THE DIAMETER IS THE RADIUS. IF YOU HAVE A LINE FOR DIAMETER, MULTIPLY BY PI TO GIVE THE CIRCUMFERENCE. TO DRAW THE CIRCLE, FOLD THE LINE IN HALF AND HOLD AT THE FOLD.
