The circumference, C, of a circle is given by the formula

The 3 times circle rule is a rule for finding the circumfrence of a circle. Basiclly, you multiply the diameter by 3.

Well, to get circumference of something, this is the rule. C=(pie symbol)d =3.14.11 So to get the answer, you would multiply 3.14 by 11, which is 34.54. Hope I helped

You cannot, there is no single-rule, formulaic relationship between mass and physical measurements like length or diameter.

The circumference, C, of a circle is given by the formula

Eg: Pi x diameter = Circumference. It is just the rule you stick by.

It's the diameter times pi.

divide dy pi. the rule is diiameter (or 2 radius) multiplied by pi equals circumference so: 2 pi x radius= circ and, since diameter is 2 times the radius, pi x D= circ

The radius is 1/2 of the diameter.

The 3 times circle rule is a rule for finding the circumfrence of a circle. Basiclly, you multiply the diameter by 3.

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, mathematicians have been able to calculate the value of to thousands of places.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.Circumference, diameter and radii are measured in linear units, such as inches and centimeters. A circle has many different radii and many different diameters, each passing through the center. A real-life example of a radius is the spoke of a bicycle wheel. A 9-inch pizza is an example of a diameter: when one makes the first cut to slice a round pizza pie in half, this cut is the diameter of the pizza. So a 9-inch pizza has a 9-inch diameter. Let's look at some examples of finding the circumference of a circle. In these examples, we will use = 3.14 to simplify our calculations.Example 1: The radius of a circle is 2 inches. What is the diameter? Solution: = 2 · (2 in) = 4 inExample 2: The diameter of a circle is 3 centimeters. What is the circumference? Solution: = 3.14 · (3 cm) = 9.42 cmExample 3: The radius of a circle is 2 inches. What is the circumference? Solution: = 2 · (2 in) = 4 in = 3.14 ·(4 in) = 12.56 inExample 4: The circumference of a circle is 15.7 centimeters. What is the diameter? Solution: 15.7 cm = 3.14 · 15.7 cm ÷ 3.14 = = 15.7 cm ÷ 3.14 = 5 cmCourtesy of Ms. Goodies Math PageA circle does not have a volume. It is a 2-dimensional thing, which has an area. and a perimeter which has a length (circumference). A cylinder, like a tube with closed ends has a volume equal to the area of the base (usually a circle, dicussed above) multiplied by the length of the cylinder.

Two methods: 1. mark a point on the circumference of the round object; put a mark on the floor; line up the marks and roll the object along the floor until the mark retouches the floor; use the meter rule to find the distance between the marks on the floor. 2. measure the diameter of the round object using the meter rule and multiply it by π (pi ≈ 3.14159)
