There is no need that the rotated side must be the base. You can rotate around the opposite side of triangle then also you will get the same cone.

If the side of 3cm is rotated, won't it become the height of the cone ?

I can't understand.

We know long side is hypotenuse according to question which will be 5cm then height is 4cm & base is 3cm then we extent the 3cm behind 4cm height as a diameter & draw the circle along this & calculate the volume from formula.

We take orderly the sides of triangle in required it is simply to calculate using formula 1/3*3.14*r^2*h.

If it is rotated about 3 cm. How could radius be 3 cm?

Is the cone with base 3 rotated (form imaginary cone shape) or is it folding it (say paper) to form cone? if so how its r=3?

@Sakshi is right. If it is rotated about 3 cm then its radius should be 3/2 = 1.5 cm.

Tell me basics of volume and surface area.

Which mean r & h?

I think 3 cm is the surface area of the circle at the base.
