Question

Volume of the cylinder whose base area is 20cm square and height is 10cm.Find​

Answer 1

here is ur answer   ..............

hope this will helps u.............

volume of cylinder =  $\pi r^{2} h$

where, r= ?

  h=10cm

given, base area => $\pi r^{2} = 20$

==>$r^{2} = 20 *22/7$

==> $r^{2} = 62.5$

==>r= $\sqrt[]{62.5}$

==> r = 7.9 cm (approx)

volume of cylinder = $\pi *(7.9)^{2} *10$

==>  $\pi *62.4 *10$

==>$\pi * 624$

==> 13728/7

==>1961.14 $cm^{3}$   (approx)

hope u got ur answer..........
