Yes and it is for any circle: circumference/diameter = pi
1/2*pi*r2
4 * pi * r * r15 Fby subcooling20The formula for calculating the area of a circle - is Pi x r x r
The formula for calculating the linear packing fraction of a material in a given space is: Linear Packing Fraction (Sum of diameters of all spheres) / (Length of the space)
Formula for calculating the area of sphere is : 4 * pi * r * r
2,,r or ,,d 2x pi x radius or Pi x Diameter
Its Area = pi * (radius ^2 - height^2)
(4/3)*pi*r^3 pi is constant 3.14, r is radius of the sphere.
6(pi)l2, where l = length of side
V=4/3*Pi*r3 where r is the radius.
Area of a circle measured in square units = pi*radius2
Pi, times, the squaire of the raidous, times hight. = volume
