JCL please kindly observe 200317`s answer in that the equation is right but there is a mistake in substitution i,e. height is 250 but 200317 has substituted as 500 and hence 200317`s answer is totally wrong
:O sorry ♥ I haven't noticed that..
Sorry for my wrong thoughts.. sorry..
it is ok yaar
height is 250 itself
Height = 50 x 5=250
radius =7cm
volume =  \pi r∧2h
   =22/7*49 *500
