Question

if the volume of cylinder is 112pie cm cube it's radius is4cm then find the curved surface area ​

Answer 1

Answer:

Curved Surface Area = 56π square cm

Step-by-step explanation:

We know that,

    Volume of cylinder = πr^2h

or, 112pie = pie(4)^2h

or, 16h = 112

or, h = 112/16 = 7 cm

Now, curved surface area of cylinder

= 2πrh

= 2π(4)(7)

= 56π square cm.

Answer 2

Answer:

56 pie cm square is the answer
