Surface Area of a Cylinder = 2 pi r 2 + 2 pi r h\n\n(h is the height of the cylinder, r is the radius of the top) \n\nSurface Area = Areas of top and bottom +Area of the side \n\nSurface Area = 2(Area of top) + (perimeter of top)* height \n\nSurface Area = 2(pi r 2) + (2 pi r)* h \n\nIn words, the easiest way is to think of a can. The surface area is the areas of all the parts needed to cover the can. That's the top, the bottom, and the paper label that wraps around the middle. \n\nYou can find the area of the top (or the bottom). That's the formula for area of a circle (pi r2). Since there is both a top and a bottom, that gets multiplied by two. \n\nThe side is like the label of the can. If you peel it off and lay it flat it will be a rectangle. The area of a rectangle is the product of the two sides. One side is the height of the can, the other side is the perimeter of the circle, since the label wraps once around the can. So the area of the rectangle is (2 pi r)* h. \n\nAdd those two parts together and you have the formula for the surface area of a cylinder. \n\nSurface Area = 2(pi r 2) + (2 pi r)* h

The formula for surface area of a sphere is \nA = 4*pi(r^2)\n64 pi = 4*pi(r^2)\nwhich means r^2 = 16 or r = 4\nVolume of a sphere is \nV = (4/3)*pi (r^3)\nV = (4/3)*pi (4^3)\nV = (4/3)*pi (64)\nV = (256/3)*pi

The volume of a cylinder is found by using the formula:\n[pi]*hr^2\nIf I were to double the radius, then I would have:\n[pi]*h*(2r)^2 = 4*[pi]*hr^2\nSo doubling the radius will make the volume four times as much.\n\nThe surface area of a cylinder is found using the formula:\n(2*[pi]*r^2) + (2*[pi]*hr)\nIf I double the radius, then I will have:\n(2*[pi]*(2r)^2) + (2*[pi]*h(2r))\n= (8*[pi]*r^2) + (4*[pi]*hr)\nIf we factor out a 2, then we have:\n2 * {(4*[pi]*r^2) + (2*[pi]*hr)}\nWhich is more than double the original.  In fact, it doubles the original volume, then adds the surface area of original ends (circles) again.

Just break the pentagon up into 5 triangles.  You can then add together the area of the 5 triangles to get the total area.

Volume = pi r^2 h \n\nMeasure a Coke can to get r and h and calculate the volume.  Plug it in for V in  the volume formula and solve it for h.\n\nThen take the surface area formula, SA = 2 pi r^2 + 2 pi r h,\nreplace the h with your answer from above, find the first derivative d(SA)/dr, and make it equal to zero to find the minimum.

I'm assuming:\nThe box has a square top and bottom.\nThe volume v is fixed.\nr is the length of a side of the top.\nh is the height of the box.\n\nv = r^2*h\nh = v/r^2\n\nThe surface area is a top and bottom both r x r and\nthe sides which are r x h.\n\nArea = 2*r^2 + 4*r*h = 2^r^2 + 4*r(v/r^2) = 2r^2 +4v/r\n\ndA/dr = 4r -4v/r^2\n\nSet to 0 and solve\n0 = 4r -4v/r^2\n\n0 = 4r^3 -4v\n0 = r^3 - v\nv = r^3, or  r = v^(1/3)\nThat means that the container is a cube.

The volume and surface area of a solid are related because the outside dimensions are the same, but the equations for volume and surface are different.\nThe equation for volume gives you units in cubic centimeters or cubic inches.  However the equation for area gives you units in SQUARE centimeters or square inches.\nBecause the volume is a cube function and the area is a square function, you can deduce that the volume increases more than the area as you increase the outside dimension.\nFor example, consider a cube where height=depth=width = 5 cm.   There are 6 sides of area 10cm*10cm = 6*100sq cm = 600 sq cm.  If we double the size, area = 6*20cm*20cm = 2400 sq cm.  The volume quadrupled when a side only doubled!\nBut the equation for the volume is h*d*w.  So the volume of the 10cm cube is 1,000 cc.  If we double a side, the volume is then 20cm*20cm*20cm = 8,000 cc.  The volume increased by 8 when a side was doubled.\nThe same thing happens when you use the equations for a sphere.  For volume, V = 3/4 pi R^3 and area A = 4 pi R^2.\n\nThis relationship is significant when you consider thermodynamics.  The heat loss/gain of an object is a function of its area but its heat content is a function of the mass (which is directly related to volume).   This is why a strand of spaghetti will cool very quickly whereas the whole pot will stay hot for an hour.

A=1/2bh is for the area of a triangle.\nV=s^3 is for the volume of a cube.

you could use a blown up ballon for volume and a flat ballon for area.........cuz volume takes up space....and area is just how big something is

To find the surface area of a cube without measuring a face, you would:\n1) Multiply: length*width\n2) Multiply: length*height\n3) Multiply: width*height\n4) Then you add those three answers up \n5) After you add them, multiply by 2 because a cube has 2 of each face.\n\nHope this helps!!

area or volume???\n\narea = 2 (3.4 * 3 + 3*2.2 + 2.2*3.4 )\n in square meters.\n\nvolm = 3.4*3*2.2\nin cubic meters.\n\n\nI only edited bcoz ever1 is giving wrong ans for area. Correct area is 48.56 sq mtr. I dont understand how it can b 6.6\n\nvolm = 22.44 cubic mtr
