A cylinder with a height of 4cm and a width of 10cm has a lateral area of about 125.66cm2
A cylinder with radius 5 and width 10 has a lateral area of about 314.16 units2
height * circumference (picture the cylinder cut along the long edge, then rolled out flat, and you would measure height * width) note: if you need to include the circles at the top and bottom of the cylinder, add (circumference / 3.1415926 )^2 * 2 * 3.1415926
Surface area is 376.99 units2
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!
length x width
divide surface area by width Sorry It is a little more complicated than that. Surface area = (2 X length X width) + (2 X length X height) + (2 X width X height) Solve for height Surface area - (2 X length X width) = 2height(length + width) (Surface area - (2 X length X width))/2(length + width) = height
Surface area = 2*(length*width + width+height + height*length) = 370.125 square units.
The volume of a cylinder if height is 8 cm and width is 4 cm is: 101 cubic cm
hi i m sunny dhiman.. The lateral surface area of cylinder will become equal to the area of rectangle now we have area of rectangle = 4224 cm^2 breadth (width) = 33cm area of rectangle = l * b 4224 = l * 33 4224/33 = l 128 = l Perimeter of rectangle = 2l+ 2b =2 (128) + 2(33) =332cm Previous answer was completely wrong. Lateral area of cylinder is 4224 sq.cm. (not cu.cm. by the way) Height is 32 cm so lateral width must be 4224/32 = 132 cm = diameter of cylinder. Perimeter of sheet is the circumference of a 132 cm cylinder = 132*Pi = 414.6902 cm. So final sheet size is 32 cm x 414.6902 cm.
Double [ (length x width) + (length x height) + (width x height) ]
it will increase more if you double the radius because the dimensions multiply and the curved surface has less area to cover as its height decreases and width increases
(height * width)/2
