d = 638mm
r = 319mm
h = 1312mm
Circumference of a Cylinder = 4*pi*r units
= 4*3.1415*319 mm
= 4008.554 mm
The circumference is about 25.13 units.
The question cannot be answered. There is no information on what aspect of the cylinder is 14 cm: the radius, diameter, circumference, height.
Divide the circumference by the value Pi - this will give you the diameter.
diameter X pi = circumference circumference X height = area
The surface area of a cylinder can be derived from the area of rectangle. If you 'unroll' a cylinder you have a shape of a rectangle, similar to a sheet of paper. The width of the rectangle will be the height of the cylinder and the length of the rectangle will be the circumference of the cylinder end.So, Area = length * widthwhere, width = height of cylinder & length = circumference of cylinder end = PI*(Diameter of cylinder)Therefore,surface area of a cylinder = (PI)*(diameter of cylinder)*(height of cylinder)Hope that helps!
Height cannot be calculated from the information given.
Divide the surface area by the circumference of the circle, which is a product of the diameter x Pi. Essentially, an unrolled cylinder is a rectangle.
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.
For a circle the diameter can be found by dividing the circumference by pi. Once the diameter is found by squaring the radius multiplied by pi. For a cylinder follow the previous method and multiply the answer by two. Multiply the circumference of the circle by the cylinder height. Add the two answers together.
The answer will depend on what the 1 metre refers to: radius, diameter or circumference.
The answer will depend on what is 20 cm: the radius, diameter or circumference.
Ah, what a lovely question! To find the circumference of a cylinder, you'll want to use the formula 2πr, where r is the radius of the cylinder. Since the diameter is 16 inches, the radius would be half of that, which is 8 inches. So, the circumference would be 2 x π x 8, which is approximately 50.24 inches. Keep painting with those happy little numbers!
