The answer is 25 I think sorry if it’s wrong :)
The volume of the cylinder having diameter 12 cm and height of 4 cm is 452
.
Given diameter of cylinder be 12 cm and height of cylinder be 4cm.
We are required to find the volume of cylinder.
Volume is the quantity of substance a container can hold in its capacity.
Diameter=12 cm
Radius=6 cm (Radius is always equal to half of diameter)
Volume of cylinder=π
We have to just put the values of r, h and π in the formula to get the volume of the cylinder.
Volume=π
=3.14*4*36
=452.57 
After rounding off we will get 452
.
Hence the volume of cylinder is 452
.
