diameter: you have stated that it is 3.14
radius: half the diameter, therefore 1.57
circumference: pi times the diameter, therefore 3.14 x 3.14 = 9.86
area: pi times the radius squared, therefore 3.14 x 2.46 = 7.72
Circumference = 2*pi*radius or diameter*pi
Circumference = 2*pi*r r(radius) * 2 = diameter So. assuming the bottle is fairly a circle, measure across the bottom to get the diameter and then divide that in half for the radius and use the circumference formula. Of course a bottle is not quite a perfect circle everywhere and you might need calculus to get a proper circumference. I am thinking vector calculus.
Measure the distance from top left corner of square (or top right) to the bottom right corner of square( or bottom left) to get the diameter of the circle. Then calculate the circumference from that figure.
Imagine the cylinder is a stack of thin plates with radius 3. The surface area of the cylinder will be the total of the circumferences (the distance around the outside) of all the plates.First, you need to figure out the circumference of a plate. Circumference equals pi (3.1415926...) times the diameter. (You can probably round pi to four digits for this problem.) The formulas in this specific case are:Circumference = pi multiplied by the diameter (3+3)Surface area = Circumference multiplied by the height of the cylinder (8)The problem doesn't indicate if the cylinder is hollow, so you may need to add the areas of the top and bottom to get the total surface area. The formula for the area of a circle is pitimes the radius squared (3x3).
the circumference of a pencil depends on its size. Also, to a certain degree of accuracy. if you want to know the circumference of the pencil with the lead inside, measure the line exactly in the middle of the circle at the bottom of the pencil and times your answer by pi. Hope this helps :s
Circumference = 2*pi*radius or diameter*pi
To determine the length of the string needed, Brenda can calculate the circumference of the circular bottom edge using the formula: circumference = π * diameter. The circumference of the lamp shade is 16π cm, so Brenda will need a string of 16π cm in length to attach the beads along the circular bottom edge.
Press your number eg 69 the press pi SIMPLES

Do you mean, how do you determine the value of pi? Use a compass to draw a circle. Measure the measure the circumference of the circle using a string. Draw the diameter and measure it. The radius is ½ the diameter. pi = Circumference ÷ radius Do this several times and calculate the average. It should be close to 3.14 You could wrap a string around a can and to measure the circumference. Then measure the diameter of the top of the can by finding the longest distance across the top. One problem with this method is the top and bottom of the can is a bit larger than the middle. Circumference divided by diameter

They stay the same circumference.
Diameter is 28 inches
Circumference is the measurement around the trunk of the tree. It is usually measured at breast height because trees flare out at the bottom at different rates based on soil conditions. The best way to measure this is with a ribbon or piece of rope. Diameter can be measured by dividing this number by pi or 3.1415
A cone does not really have a base but if you find the circumference of the bottom that is the base.
The circumference of the Earth at the Equator is 40,075.02 kilometres, or 40,075,020 meters.
