11 is a good approximation of the diameter. If the circumference is 35, the actual diameter is about 11.14 (35/3.1416).
to divide a pipe into sections measure the outside diameter then multiply by 3.142 this will give you the circumference divide this number by how many sections you require place a mark anywhere on the on the pipe then measure from that mark your answer The best method for calculating the cross section area of a round pipe or tube is to use the following formula: ((D-W)*W)*PI Where as D= Outside Diameter Measurement W= Wall Thickness PI= 3.1416 that is circumference. The answer I have is: diameter squared x .7854 Ex. 3inch pipe (inside diameter) 3 x 3 x .7854= 7.0686
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.
For circumference, multiply the diameter by pi and round the product to the second decimal place. For area, multiply the square of the radius by pi and round the product to the second decimal place.
The circumference of a circle is pi * the diameter. The diameter is radius * 2. The area of a circle is pi * the radius squared. So for a circle of circumference 62.8 ft, the radius is 62.8/pi/2 which is 10.0 ft to 1 decimal place The area is pi * radius squared = 314.2 sq ft.
Pi is the ratio between the circumference of a circle and its diameter. The first and most obvious way to find pi is to measure both the circumference and the diameter. This gives a very rough approximation. A second way is to use geometry. By fitting regular shapes with large numbers of sides both around and inside the circle we can narrow the boundary for the potential value of pi. The most accurate way to find pi is to do with its use in certain very complex formulae. Computers are required to determine pi to an infinite decimal place.
If a circle has a diameter of 6 the circumference is about 18.9
circumference = pi x diameter. So rearranging gives diameter = circumference / pi So diameter = 6/pi = 1.9 inches (1 decimal place)
Circumference = pi x diameter. So the circumference of a circle with diameter 12 cm = pi x 12 = 37.7 cm (1 decimal place.)
Circumference of plate: 4.3*pi = 13.5 rounded to one decimal place

There is a place inthe Bible that mentions a circular pool, with a diameter of 10 units and a circumference of 30 units. This suggests that the author believed the ratio of circumference to diameter to be 3.
Circumference of a circle = 2*pi*radius or pi*diameter Circumference = pi*4.2 = 13.19468915 or 13.2 cm to one decimal place
Circumference = n (pi) x diameter The diameter always equals 2 x radius. So the diameter of this circle is 5. Multiply by pi. 5 x 3.142.. = 15.7 to the nearest decimal place
Assume pi is 3.14 Therefore: Circumference = 3.14 x 15dia = 47.1cm
65 x pi = 204.2cm to one decimal place.
