![]() ![]() Given the area of a circle calculate the radius, circumference and diameter. Putting A, C and d in terms of r the equations are: Given the radius of a circle calculate the area, circumference and diameter. Using the formulas above and additional formulas you can calculate properties of a given circle for any given variable. Any other base unit can be substituted.Ĭircle Formulas in terms of Pi π, radius r, and diameter d Radius and Diameter: The units are in place to give an indication of the order of the results such as ft, ft 2 or ft 3. Units: Note that units of length are shown for convenience. Given any one variable A, C, r or d of a circle you can calculate the other three unknowns. Given height and volume calculate the radius, lateral surface area and total surface area.Use this circle calculator to find the area, circumference, radius or diameter of a circle.3 0, cos x dx sin x 3 0.346 5735 by calculator 0.347 to three. Given height and lateral surface area calculate the radius, volume and total surface area. COS X -tan x 1/3 tanx dx - log, ( cos x ) 4 TV / 4 -log -108.Given radius and lateral surface area calculate the height, volume and total surface area.Given radius and volume calculate the height, lateral surface area and total surface area.Given radius and height calculate the volume, lateral surface area and total surface area.but using your calculator is the more efficient method. Use the following additional formulas along with the formulas above. and solve for drdt: dV dt 2 dr dt 2 dr dt dr dt 4 3 45 3 100 r. You can do this using theĬircle calculator. To calculate the total surface area you will need to also calculate the area of the top and bottom. ** The area calculated is only the lateral surface of the outer cylinder wall. A = L + T + B = 2 πrh + 2( πr 2) = 2 πr(h+r) For example, if you are starting with mm and you know r in mm, your calculations will result with A in mm 2, V in mm 3 and C in mm.Total surface area of a closed cylinder is:.Calculate the top and bottom surface area of a cylinder (2.Calculate the lateral surface area of a cylinder (just the curved outside)**:.Calculations are based on algebraic manipulation of these standard formulas. For example, if you are starting with mm and you know r and h in mm, your calculations will result with V in mm 3, L in mm 2, T in mm 2, B in mm 2 and A in mm 2.īelow are the standard formulas for a cylinder. Define pi with more digits, and shorten the result so that it shows the actual precision. ![]() The units are in place to give an indication of the order of the results such as ft, ft 2 or ft 3. You're displaying results with maximum 'precision' but basing them on a value of pi that has only four significant figures. Units: Note that units are shown for convenience but do not affect the calculations. This is a right circular cylinder where the top and bottom surfaces are parallel but it is commonly referred to as a "cylinder." It will also calculate those properties in terms of PI π. Cone (1 / 3) r 2 h (1/3)\pi r2h (1/3) r 2 h, where r r r is the radius and h h h is the height. Cylinder r 2 h \pi r2h r 2 h, where r r r is the radius and h h h is the height. Surface Area 4 × × r 2 Radius of a Sphere Captain Calculator. This online calculator will calculate the 3 unknown values of a sphere given any 1 known. Here is such a program: PROGRAM:ARCHPI : 6N : 1S : 2/ 3 T : For (I,1,10) : Disp N. Sphere (4 / 3) r 3 (4/3)\pi r3 (4/3) r 3, where r r r is the radius. To find the volume of the sphere, the equation is V 4/3 r (or pi r)3, where r is. This online calculator will calculate the various properties of a cylinder given 2 known values.
