If the length of radius of a right circular cylinder is 2 units, then the numerical value of volume and surface area of cylinder will be equal for any height .

Answer

1

Explanation

True , since volume `= pi 2^(2) h, h =` height of the cylinder , surface area `= 2 pi .2h = 4 pi h` sq-cm.
But the numerical value of `pi.2^( 2)h` cc `=4 pi h` and of `2.pi.2.h` sq-cm`= 4 pi h` are equal.
Hence the statement is true .
