(CD - ab)^2 = (CD - ab)(CD - ab) = c^2 d^2 - 2abcd + a^2b^2 Try it with say a = 4, b = 3, c = 2 & d = 1: Then CD = 2 and ab = 12 so CD - ab = -10 and squared = 100 c^2 = 4 d^2 = 1 so c^2d^2 = 4 x 1 = 4 a^2 = 16 b^2 = 9 so a^2b^2 = 16 x 9 =144 2abcd = 48 giving 4 - 48 + 144 = 100. Shazam!
If a, b, c and d are all non-zero then ab = CD if and only if a/c = d/b or (equivalently) a/d = b/c
Given the formula D = ABC, what is the formula for C?Answer: C = D ÷ AB
if the diameter is 56, then C = pi x d = 3.14 x 56 = 175.84 feet
