What is the total area of a cylinder with a radius of 8cm and a height of 8cm?
I presume you mean total surface area of the cylinder:Area = 2πr(r + h)= 2π8(8 + 8)= 256π cm2~= 804.25 cm2The cylinder consists of 2 circular disks at each end and the curved surface.The area of each of the disks is πr2.To work out the area of the curved surface, imagine cutting the cylinder from end to end and flattening out the edge; then it will be a rectangle with length the height of the cylinder and width the perimeter of the circular end. Thus its area is 2πrhThus the total surface area of the cylinder is:area = πr2 + πr2 + 2πrh= 2πr2 + 2πrh= 2πr(r + h)
How do you draw a net for a three dimensional figure and the figure is a right circular cylinder?
Draw a rectangle for the side of the cylinder and on top and bottom of this rectangle 2 circles for the base and the top of the cylinder The rectangle width would be the diameter of the circle large and the same height that the cylinder
What is the surface area of a box that is 7.75x5.5x10.75?
Surface area = 2*(length*width + width+height + height*length) = 370.125 square units.
Will the surface area of a cylinder increase more if you double the height or double the radius?
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
How do you find the area of 1 face of a cylinder?
Faces of cylinder are circular therefore area must be pi*radius*radius That is the formula for the top and bottom faces, the circles. However, the main face, the face connecting the two circles, is really a large rectangle bended to fit with the circles. The height of the rectangle is the same as the height of the cylinder. The width of the rectangle is the circumference of the circle (pi * 2 * radius). The formula for a rectangle is width * height. So, the side face is height of cylinder * circumference of circle (pi * 2 * radius.)
What is the lateral surface area of a cylinder with a height of 4cm and a width of 10cm?
A cylinder with a height of 4cm and a width of 10cm has a lateral area of about 125.66cm2
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!

Thus its area is 2πrhThus the total surface area of the cylinder is:area = πr2 + πr2 + 2πrh= 2πr2 + 2πrh= 2πr(r + h)
How do you do the surface area for a cylinder?
Let the cylinder have circular ends of radius r and height h. There are two circular ends which each have an area of {pi}r2, and the curved side of the cylinder; if a cut was made down it from one end to the other, it could be "unrolled" into a rectangle with its length the height of the cylinder, and width the perimeter of one of the ends which is given by 2{pi}r, giving an area of 2{pi}rh.. Surface area = 2 x area_of_end + area_of_side = 2 {pi} r2 + 2 {pi} r h = 2 {pi} r (r + h)
How do you find the height of a box given the width depth and surface area?
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
What is the volume of a cylinder if height is 8 centimeters and width is 4 centimeters?
The volume of a cylinder if height is 8 cm and width is 4 cm is: 101 cubic cm

Surface area = 2*(length*width + width+height + height*length) = 370.125 square units.
Will the surface area of a cylinder increase more if you double the height or double the radius?
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
