How do you find the radius of a cylinder using the circumference and the width?
If you know the circumference then divide that by (2 x pi) and you will get the radius. The width is unnecessary information.
Find the volume of the cylinder the radius is 6 in and the width is 12 in?
Volume = pi*r*w = pi*62*12 = 1357.2 inches3
How do you derive of surface area of cylinder?
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!
Is a cylinder a 3 D shape?
Yes! It is in three dimensions because it has height, width and depth.
How do you find the diameter of a circle with the width and length?
The width, or the length of a circle are its diameter.
