Answer 1

Hi.

Good question...Keep progressing...

Here is your answer---

Given---

Height of the cylinder(h) = 14 cm.
      Curved surface area of cylinder = 2 π r h
                                             704 = 2 x (22/7) x r x 14
                                                 r = 8 cm.

Using Formula,
   Volume of the Cylinder = π r^2 h
                                           = (22/7)x 8 x 8 x 14
                                           = 2816 cm^3

Thus, volume of the cylinder is 2816 cm^3.

Answer 2

Answer:

So the volume is 2816 cm³

Step-by-step explanation:

CSA = 704 sq.cm

h = 14cm

CSA = 2πrh

704  = 2 x22/7 x r  14

704/88=  r

r=8cm

V =πr²h

   = 22/7 x 8x8x14

   =   2816 cm³
