Question

the difference between outside and inside surface of cylindrical​

Answer 1

• Curved surface area of the outer cylinder and Curved surface area of the inner cylinder = 2πRh - 2πrh. Given: difference between the outside and inside curved surface area of cylinder= 44 cm2 . Volume of cylindrical metallic pipe = πR²h - πr²h.

its real fact about inner side and outer side

Answer 2

Answer:

Outside surface area = 2*pie*R*h
Inner surface area = 2*pie*r*h
Difference = 2*pie*R*h- 2*pie*r*h
= 2*pie*h(R-r)
