Question

The diameter of the base of right circular
cylinder is 2r and its height is h. The volume of
cylinder is :​

Answer 1

Answer:

$\huge\boxed{\fcolorbox{red}{pink}{Answer :- }}$

Radius = Diameter/2 = 2r / 2 = r units

and height is given h units.

Therefore Volume if the cylinder

$= \pi {r}^{2} h \: {unit}^{3}$

Answer 2

Step-by-step explanation:

r=d/2

so, radius =r

since the cylinder's base and top is always same,

so, volume = πr^2h

then, putting value of π =22/7

then, 22/7*r*r*h

hence, the volume is 22/7r^2h unit^3
