Copy and complete the table. π = 22 7 Curved surface cm 2 24200 Radius (cm) 35 Height (cm) ?

From the given, Curved surface area of a cylinder = 24200 cm 2 The radius of a cylinder = 35 cm The height of a cylinder = ? We know that, The curved or lateral surface area of a cylinder is, CSA = 2 πrh ⇒ 24200 = 2 × 22 7 × 35 5 × h ⇒ 24200 = 220 × h ⇒ h = 24200 220 ⇒ h = 110 cm Hence, the height of a cylinder is 110 cm . And the completed table is given below. Curved surface cm 2 24200 Radius cm 35 Height cm 110
