WebLet radius of cylinder be ‘r’ Let height of cylinder be ‘h’ Curved surface area of cylinder / total surface area of cylinder = 1/2 2πrh / 2πr (h+r) = 1/2 h/(h+r) = 1/2 2h = h+r 2h – h = r h = r Height = Radius Hence proved. 9. The curved surface area of a cylinder is 1320 cm2 and its base has diameter 21 WebVerified answer. I would set the equation equal to zero: 2πr^2 + 2πhr - s = 0. Use quadratic formula: a=2π. b=2πh. c=-s. r= (-2πh (+/-)sqrt ( (2πh)^2-4*2π*-s)/ (2*2π) a little …

WebThe radius ‘r’ of a cylinder is the radius of its base. Now, the area of the rectangle = length × breadth. 2πr is the circumference of the circle and h is the height. Area of the curved surface will be = 2πr × h = 2πrh. So the area of the cylinder will be: 2πr² + 2πrh, or. Total Surface Area of Cylinder = 2πr ( r + h ) WebDec 1, 2024 · A Computer Science portal for geeks.

WebRadius of the base of the cylinder = r = 0.7 m (Given) Curved surface area of cylinder = C.S.A = 4.4m 2 (Given) Let ‘h’ be the height of the cylinder. We know, curved surface area of a cylinder = 2πrh Therefore, 2πrh = 4.4 2 x 3.14 x 0.7 x h = 4.4 [using π=3.14 ] or h = 1 Therefore the height of the cylinder is 1 m. WebStep-by-step solution. Step 1 of 5. Consider the formula as defined below. To solve the above formula for a specified variable isolate the variable term on one side of the equation, with all other variables and constants on the opposite side as shown below. WebSA = 2πrh + 2πr2 d dh SA = 2πh + 2πr + 4πr dr dr The calculation of dh dr using implicit differentiation is identical to the calcu lation in part (a): V = πr2h + 2 πr3 3 dV dh = πr2 + 2πrh + 2πr2 dr dr 0 = dh πr2 + 2πrh + 2πr2 dr −πr2 dh = 2πrh + 2πr2 dr dh h + r dr = −2 · r. Plugging in, we find: d dh how to see clip tray
