WebMar 9, 2024 · This scientific guide says: "The effective diameter (De) is defined in a way that is universal for both ice and water clouds, which is essentially the photon path characterizing the PSD (Mitchell 2002): De = (3/2) * IWC / ( * ) where is the ice water content (g/cm:math:^3), is the bulk ice density (0.917 g/cm ) and is the total projected area ... WebWe know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. So add 21 to both sides to get the constant term to the righthand side of the equation. x^2 + y^2 -4y = 21. Then complete the square for the y terms. x^2 + y^2 - 4y + 4 = 21 + 4. forest grove forest schoolWebJan 16, 2024 · The formula for radius to area is: A=\pi {r}^ {2} A = πr2 How to find radius from area How to find radius from diameter If you know the diameter of a circle, you can find its radius by dividing the diameter by 2: r=\frac {d} {2} r = 2d This is the simplest formula you can use to get the radius.
