Is the diameter of a circle bigger or smaller then the radius?
The diameter is twice as long as the radius. d = 2r The diameter is basically a line through the center of a circle while a radius is from the center to the circumference of a circle.
What is the circumference of a circle?
The circumference is the distance around the circle, its "perimeter."The circumference of a circle is equal to π times the diameter of the circle (C = πd), or π times twice the radius of the circle (C = 2πr).The circumference is the distance around itIf you know the diameter (width) of the circle, you can use the formulaCircumference= Diameter x pi (approx 3.1416)Example : if a circle has a diameter of 5 cm then the circumference is 5 x π =5π (about 15.7 cm)The actual formula relates to the radius of the circle, which is half the diameter.Radius Formula : C = 2πr (2 pi times the radius)As long you remember the formula you should be fine....Circumference = 2 * pi * rOr pi * dwhere r = radius & d = diameter of the circle.Also pi (=3.143) can be roughly put down as 22/7 if you more comfy with fractions than the decimals.the equation is 2*pi*rr being the radius
What iS the radius of a circle with circumference?
A circle is a shape with all points the same distance from the center. It is named by the center. The circle to the left is called circle A since the center is at point A. If you measure the distance around a circle and divide it by the distance across the circle through the center, you will always come close to a particular value, depending upon the accuracy of your measurement. This value is approximately 3.14159265358979323846... We use the Greek letter (pronounced Pi) to represent this value. The number goes on forever. However, using computers, has been calculated to over 1 trillion digits past the decimal point.The distance around a circle is called the circumference. The distance across a circle through the center is called the diameter. is the ratio of the circumference of a circle to the diameter. Thus, for any circle, if you divide the circumference by the diameter, you get a value close to . This relationship is expressed in the following formula:where is circumference and is diameter. You can test this formula at home with a round dinner plate. If you measure the circumference and the diameter of the plate and then divide by , your quotient should come close to . Another way to write this formula is: where · means multiply. This second formula is commonly used in problems where the diameter is given and the circumference is not known (see the examples below).The radius of a circle is the distance from the center of a circle to any point on the circle. If you place two radii end-to-end in a circle, you would have the same length as one diameter. Thus, the diameter of a circle is twice as long as the radius. This relationship is expressed in the following formula: , where is the diameter and is the radius.
