WebRadius of cylinder = 3.5 cm So, curved surface area of cylinder = 2πrh = cm2 Total surface area = 2πr(h+r) = cm2 So, 8. Question The total surface area of a hollow metal cylinder, open at both ends of external radius 8 cm and height 10 cm is 338 p cm2. Taking r to be inner radius, obtain an equation in r and use it to obtain the WebQ. A solid cylinder has a total surface area of 462 cm².If its curved surface area is one third of its total surface area, find the radius and height of the ...
Surface Area of a Cylinder Calculator Formula
WebFormula for calculating the Curved Surface Area (C.S.A.)- Consider a cylinder having a height ‘h’ and base radius ‘r’. The curved surface area of a cylinder is given as- C.S.A.= Example- Consider a curved surface area of a cylinder having height of 5 cm and diameter of base to be 2 cm. Solution- Given h = 5 cm, and d = 2 cm, thus r = 1 cm C.S.A. = WebA solid cylinder has a total surface area of 462 cm 2. Its curved surface area is one-third of its total surface area. Find the radius and height of the cylinder. (Take π = 3.14). Solution: Given that. Curved or lateral surface area = 13 * total surface area. 2πrh = 1/3 (2πrh + 2πr 2) 4πrh = 2πr 2. 2h = r. Total surface area = 462 cm 2 military working dog handler training manual
Chapter 19: Surface Area And Volume of a Right Circular Cylinder ...
WebTotal Surface Area of the cylinder = 462 cm 2. Curved Surface Area (CSA) = Total Surface Area (TSA) We have to find the radius and the height of the cylinder. Using the given data, … WebFeb 20, 2024 · Best answer Total surface area = 231 cm2 As per given statement: Curved surface area = 2 3 2 3 (Total surface area) Curved surface area = 2 3 2 3 x 231 = 154 So, Curved surface area = 154 cm2 … (1) We know, Curved surface area of cylinder = 2πrh + 2πr2 Or 2πrh + 2πr2 = 231 ….. (2) Here 2πrh is the curved surface area, so using (1), we … WebApr 1, 2024 · The total surface area of a cylinder is 462 c m 2 and its curved surface area is 1 3 of its total surface area So curved surface area we can find with help of given total surface area So curved surface area = 1 3 × ( total surface area of a cylinder) ∴ curved surface area = 1 3 × ( 462) On solving ∴ curved surface area = 154 c m 2 (1) military working dogs adoption
