Question

There is circular base with circumference 30.8 cm on which a cylindrical structure is standing with lateral surface areas equals to 289.52 cm2 . what will be the height of this cylindrical structure?

Answer 1

Answer:

given = circumference of circle = 2πr = 13.8 cm

lateral surface area = 2πrh = 289.52 CM square

2πrh = 289.52 cm^2

2πr × h = 289.52

put the value 2πr = 13.8

13.8 × h = 289.52

h = 289.52 / 13.8

so, h = 20.9797

h = 21 Approx
