The circumference of the TOP of a watermelon is 0.
Top diameter at 1.75" and the height at 2.25"
Surface Area = (Circumference)(Height)* Volume = ∏r2 x Height *If you want to include the top and the bottom in the surface area of the column you have to add the area of the top and bottom. So, the Total Surface Area = [(Circumference)(Height)] + 4(∏)(Radius2)
Pi is used to find a lot of things, volume, area, diameter, radius, but most commonly, circumference. To do that, you multiply the diameter of a circle by pi, (3.14159) then you have the circumference.it is used to calculate the area and volume of a circle or cylinderalso to find circumferenceEX:DIAMETER X PI = CIRCUMFERENCE+++True but I'd question the "most commonly" because Pi is also fundamental to a huge range of calculations involving motion or force in circular or circle-function paths, and to harmonic calculations (sound, vibration, electrical circuit laws, etc.).'Incidentally, there is a neat trick by pure co-incidence worth knowing if you often use a calculator or the calculator pad on a PC keyboard to find areas of circles from their diameters. The standard formula is Pi*R^2 where R is the circle's radius, but since 2R = Diameter the formula w.r.t Diameter is therefore (Pi*D^2)/4. Now, Pi/4 = 0.7854 to enough decimal places for most everyday calculations, so then the formula simplifies to 0.7854*D^2. Look at your keypad and you see those 4 digits sit in a tidy square in the top left, nice and easy to find if you need to keep entering them!
For the string to wrap around the cylinder and yet do so by "coiling" around the outside of the cylinder from bottom to top, it will need to be 150cm long.
We're assuming the table and cloth are round? The cloth is a circle with a diameter of 90 inches - 30 from the floor to the table, 30 more across the table, and 30 more to get back down to the floor. The circumference of a circle is pi times the diameter. Do the math!
30" is the Diameter ~ 18.75*pi = 58.905 sq. ft.30" is the Circumference ~ 18.75/pi = 5.968 sq. ft.

The circumference of the top of a plastic cup is the distance around its circular opening. This can be calculated using the formula: Circumference = π x diameter. Simply measure the diameter of the top of the cup and multiply it by π (approximately 3.14) to find the circumference.
The circumference of the TOP of a watermelon is 0.
This bag has a nine inch top diameter.

According to eHow, your base area must support at least 1/3 of the table top area.
Diameter is 28 inches
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
Three 0.50 inch diameter pipes will fit into one 1.50 inch diameter pipe (hypothetically). The 0.50 inch diameters stack on top of each other until you have 1.50 inches!
