Question

find the curved surface are of cylinder of height 3h and radius r/6 (pls be quick) ​

Answer 1

Answer:

the surface are is equal to 113.14

Step-by-step explanation:

As we know that, curved surface area of cylinder = 2πrh

where height (h) = 3 and radius (r) = 6

= 2 × ( 2 2 / 7 ) × 6 × 3

= 792 / 7

= 113.14

Answer 2

Given :  Cylinder of height 3h  and radius r/6

To Find : curved surface are of cylinder

Solution:

curved surface are of cylinder  = 2 π ( Radius) (Height)

Radius = r/6

Height = 3h

curved surface are of cylinder  = 2 π (r/6)3h

= πrh

curved surface are of cylinder  = πrh  sq units
