r = radius h = elevation V = volume together = lateral surface area T = optimal surface area B = base surface area A = full surface area π = pi = 3.1415926535898 √ = square root

Calculator Use

This virtual calculator will certainly calculate the assorted properties the a cylinder offered 2 known values. The will also calculate those nature in regards to PI π. This is a right circular cylinder wherein the top and bottom surfaces room parallel but it is frequently referred to as a "cylinder."

Units: note that units are displayed for convenience but do not influence the calculations. The units space in ar to provide an clues of the order of the results such as ft, ft2 or ft3. For example, if friend are beginning with mm and you understand r and h in mm, your calculations will an outcome with V in mm3, together in mm2, T in mm2, B in mm2 and also A in mm2.

Below space the standard formulas because that a cylinder. Calculations are based on algebraic manipulation that these traditional formulas.

Cylinder recipe in terms of r and also h:

calculate volume of a cylinder: V = πr2h calculate the lateral surface ar area of a cylinder (just the curved outside)**: l = 2πrh calculation the top and bottom surface ar area of a cylinder (2 circles): T = B = πr2 full surface area of a closeup of the door cylinder is: A = together + T + B = 2πrh + 2(πr2) = 2πr(h+r)

** The area calculated is only the lateral surface ar of the external cylinder wall. To calculation the total surface area friend will require to likewise calculate the area of the top and bottom. You deserve to do this making use of the one calculator.

Cylinder Calculations:

Use the following added formulas in addition to the formulas above.

offered radius and height calculation the volume, lateral surface area and total surface area. calculate V, L, A | offered r, h use the formulas above offered radius and volume calculation the height, lateral surface ar area and also total surface area. calculation h, L, A | given r, V h = V / πr2 provided radius and lateral surface ar area calculate the height, volume and total surface area. calculation h, V, A | given r, l h = L/2πr given height and lateral surface ar area calculate the radius, volume and total surface ar area. calculate r, V, A | offered h, l r = L/2πh provided height and volume calculate the radius, lateral surface area and total surface ar area. calculate r, L, A | offered h, V $r = √( V / πh )
