WebMay 7, 2016 · 0 = 2πr2 + 2πrh − A. If we take out the 2π and h, we get this simple equation: 0 = r2 + r −A. We know that 2π, h, and A are constants, so what we have here is a … WebOr 2πh (r 1 + r 2) + 2 x 115.5 = 4620 (Using equation (1) and h = 7 cm) or 2π7 (r 1 + r 2 ... (T.S.A) = 2πr(r+h) And, Curved surface area of a cylinder(C.S.A) = 2πrh Now, Ratio between the total surface area of a cylinder to its curved surface area is T.S.A/C.S.A = 2πr(r+h)/2πrh = (r + h)/h = (3.5 + 7.5)/7.5 = 11/7.5 = 22/15 or 22:15 ...
