Answered by vaibhavdealer

height of cylinder frmed by 50 such circular plates =.5*50=25
radius =7
volume= $\pi$ r^2h
22/7*49*25=3850cmcube

:)

vaibhavdealer: if you will keep the circles on upon another ,their thickness will contribute to make the height of the cylinder
just like carrom in which the round coins of some thikness are kept on one anotther to make a cylinder

yasummu: yes right but 5*50 = 250 kindly change it and then your final answer will be 38500 cm ^3

JCL: 200317's answer is correct.. your equation is right but the answer is just wrong..

yasummu: 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

JCL: :O sorry ♥ I haven't noticed that..

JCL: Sorry for my wrong thoughts.. sorry..

yasummu: it is ok yaar

200317: height is 250 itself

Answered by 200317

height = 50 x 5=250
radius =7cm
volume = $\pi$ r∧2h
=22/7*49 *500
=7700
