What is a rule to describe how to estimate the circumference of a circle when you know its diameter?
The circumference, C, of a circle is given by the formula
What is the 3 times circle rule?
The 3 times circle rule is a rule for finding the circumfrence of a circle. Basiclly, you multiply the diameter by 3.
What is the circumference of 11 m?
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
What is a rule for finding the radius of a circle when you know the diameter?
Help i dont know
How do you find the length of a rod given the diameter and the mass?
You cannot, there is no single-rule, formulaic relationship between mass and physical measurements like length or diameter.
What is a rule to describe how to estimate the circumference of a circle when you know its diameter?
The circumference, C, of a circle is given by the formula
What is the maths meaning for rule?
Eg: Pi x diameter = Circumference. It is just the rule you stick by.
What is the rule to calculate the circumference of a circle?
It's the diameter times pi.
What is the diameter of a circle if the circumference is 7?
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
What is the rule for finding the radius when you have diameter?
The radius is 1/2 of the diameter.
How do you write a rule as an equation?
Write an equation of 3/8×112
What is the 3 times circle rule?
The 3 times circle rule is a rule for finding the circumfrence of a circle. Basiclly, you multiply the diameter by 3.
Why is measuring tape more suitable instrument than a metre rule to measure head circumference?
A measuring tape is flexible - a metre rule isn't !
What is the Formular for the area of a circle?
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.

How do you measure a round object by using a meter rule?
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)
