H= v over pie r to the second
A cylinder has 2 circular ends and the curved side. If the cylinder was a drinks can, then it could be cut down from one ciircular end to the other and the side uncurled to give a rectangle with one dimension the height of the cylinder and the other the circumference of the circular end. Thus the surface area of a cylinder is twice the area of an end plus the circumference of the end times the height of the cylinder: area = 2{pi}r2 + 2{pi}rh = 2{pi}r(r + h) = 2{pi}6(6 + 30) = 12{pi}36 = 432{pi} ~= 1357.2 cm2
2 times pi times the radius squared plus 2 times pi times the radius times the height equals surface area of a cylinder :]
volume = pi*radius2*height Rearrange the formula by dividing all terms by pi*radius2: height = volume/pi*radius2 height = 14137/pi*36 = 124.9985239 cm. Therefore: height = 125 cm to the nearest cm.
X= (3/5 , -2)
To calculate a percent, use the following formula: Part / Whole * 100 43 / 166 *100 = 25.9%
rc = d/2Radius equals diameter divided by 2.In a right circular cylinder there are 2 circles - one of the base and one on the top of the cylinder. If we are going to get the radius of one of them, it will be equal to one-half the measure of the diameter of the whole circle, or r = d/2.
Formula for the volume of a cylinder.
Divided into 3 sections (the rounded middle-section and the two circular ends), the surface afrea is equal to the area of the circular end multiplied by two (which equals pi X the radius of the circle squared) plus the circumference of the circular end multiplied by the length of the cylinder. Therefore total surface area = 2(pi X radius squared) + length(pi X 2 X radius)
Volume equals pi times radius2 times height

Then it will not be treated as a formula. It will appear literally as you type it. Because cell references and functions begin with letters Excel needs the equals sign to tell it that what is following is a formula and not just a piece of text. You can actually also start a formula with a plus sign or minus sign, but an equals sign will automatically be added.
V = {pi} r2 h is the formula for the volume (V) of a cylinder of radius r and height h.
volume = pi*radius2*height Rearrange the formula by dividing all terms by pi*radius2: height = volume/pi*radius2 height = 14137/pi*36 = 124.9985239 cm. Therefore: height = 125 cm to the nearest cm.
Put the power in milliwatts in cell A2, and then use the following formula to get the power in dBm. =10 * LOG(A2)
