Question

the height of a cylinder is 14 cm and its surface area is 704 square cm find its volume

Answer 1

hiii!!!

here's ur answer...

I think it's curved surface area is 704cm² kindly check it question once

given the height of the cylinder = 14cm

if it's curved surface area, then ans is...

curved surface area of the cylinder = 704cm²

therefore 2πrh = 704cm²

==> 2 × 22/7 × r × 14 = 704cm²

==> 44 × r × 2 = 704cm²

==> 88 × r = 704cm²

==> r = 704/88

==> r = 8cm

we got it's radius, now we will find it's volume.

volume of the cylinder = πr²h

= 22/7 × 8 × 8 × 14

= 22 × 8 × 8 × 2

= 2816cm³

hope this helps..!!

Answer 2

Answer:

So the volume is 2816 cm3 3

Step-by-step explanation:

CSA = 704 sq.cm

h = 14cm

CSA = 2th

704 = 2 x22/7 xr 14

704/88= r

r=8cm

V = r2h

= 22/7 x 8x8x14

!! 2816 cm3

Hope it helps!!!!!!
