We assume the surface area of a cylinder excluding its ends. Area = height of cylinder multiplied by circumference. That is A = h x Pi x diameter.
Volume of a cylinder = pi*r2*h So, I assume you mean 8' in diameter, which is 4' in radius. Volume = pi(4')2(6') = 302 cubic feet in volume ----------------------------------
Assume that nickels are measured in diameter, and we want to form the certain number of nickels to form an inch. Let the diameter of the nickel be 22 millimeters, which is 2.2 centimeters. Note that 1 inch = 2.54 centimeters. Then, there is no definite number of nickels that exactly form an inch since: 2.54 centimeters * 1 nickel / 2.2 centimeters = 1.15... nickels [and we obtain the "incomplete" nickel to form an inch]!
More data is required. I assume the drum has the form of a cylinder; the volume of a cylinder is calculated as pi x radius squared times height. Different combinations of radios and height can give the same volume.
I assume you want the formula for finding the circumference of a circle with a known diameter?The formula is C = pxdC = Circumferencep = Pi (3.14)d = DiameterFor example: with a diameter of 6 : 3.14 x 6 = 18.84

I'm not sure what you mean by "length" of a circle. I'm going to take a wild guessand assume you mean the distance around the circle.The circumference of a circle (distance around it) is (pi) x (diameter).If the diameter is 16 centimeters, then the circumference is 16 pi = 50.2655 centimeters. (rounded)

The diameter of a circle is a straight line passing through the center of the circle and connecting two points on the circumference. The length of the diameter is equal to twice the radius of the circle. If we assume the diameter is 1 unit, then it would be equivalent to 1 centimeter. Therefore, there are 1 centimeter in 1 diameter.
I assume you want to find out how much water fits in the hose. Treat the hose as a cylinder - that should be a good approximation, even when you bend it. Measure the length and the interior diameter. Divide the diameter by 2 to get the radius. Convert everything to feet, and finally use the formula for a cylinder to get the volume.
I assume you mean "centimeters". You multiply the number of meters by 100.
Answer 1It is necessary to assume that the shape is a sphere, since that is the only shape whose volume is determined by only its radius/diameter.Radius = Diameter/2Volume = 4/3*pi*r3 or 1/6*pi*d3Weight = Density*VolumeAnswer 2If you are given length as well as diameter, the object could be in the shape of a cylinder. The formula for the volume of a cylinder is V = (pi)r2h. Use the formulas for radius and weight given in answer 1.
I assume that you are referring to the area of a circle. You divide the diameter in half to find the radius and then you put it into the formula.
Diameter, I assume. That would be a neutron star.
Let me assume some data, and you can follow the procedure. cylinder length (l)= 3 m cylinder radius (r)= 0.5 m cylinder volume= l*r^2*Pi=3*0.5^2*3.14= 2.355 m^3 hence, the weight that the cylinder can support= cylinder volume * density of water = 2.355 * 1000 = 2355 (kg) As you can see, you can build your calculations on a certain cylinder length and you will get the diameter, or vice versa.
