Question

If the radius of a solid cylinder and its height are r time and h time respectively, find the volume of the cylinder​

Answer 1

$\: \: \: \: \: \: \: \: \: \:$

Answer 2

Volume of solid is Area • gravity for that solid

Here area of cylinder is 2 pie r h

Where h is hight

Now gravity of cylinder

Volume = mgh
= A • G (Assuming h is equals to 0)

Here derivative against time

= A^ • G^ • T^

I hope it will help you
