Solution : Total surface area A = 1/4π or, 4πr2 = 1/4π or, r2 = (1/4π)2 or, r = 1/4π cm And Volume V = 4/3 πr3 = 4/3 * π * (1/4π)3 .....
Solution : Volume of cylinder V = 41580 cm3 radius of cylinder r = 21 cm V = πr2h or, 41580 = 22/7 * 212 * h or, h = 30 cm Now, Circumference of cylinder C = 2πr = 2 * 22/7 * 21 = 132 cm So, length of rectangular chartpaper = C = 132 .....
