Question

Find the volume of the cylinder if height (h) and radius of the bas (r) are as given below:(1) r=2.5,h=7m​

Answer 1

pieXr²h

22/7X2. 5x7

22*2.5= 55

Answer 2

Given :-

• Height of cylinder -7m
• radius of cylinder -2.5 m

To find :-

• volume of cylinder ?

solution :-

As we know ,volume of cylinder is πr²h

put value in formula

=>πr²h

=>22/7×2.5×7

=>22×2.5

=>55 cubic meter

Hence ,The volume is 55 cubic meter

,

★Total surface area of cylinder is

=> 2πrh+2πr²

=>2πr(h+r)

,

★Curved surface area /Lateral surface area of cylinder is

=>2πrh

,

★Volume of cylinder is

=>πr²h
