Question

find the volume of the cylinder
circumference of the cylinder=1.32m
height=25cm

Answer 1

Hii There!!!


Given, Circumference of cylinder = 1.32 m = 132cm

Height ( h ) = 25 cm


Since, we know that

Circumference = 2 × π × r

=> 2πr = 132


=> r = 132 × 7/22 × 1/2

=> r = 21 cm



Now, Volume of right circular cylinder = πr^2h

=> 22/7 × 21 × 21 × 25


=> 34560 cm^3


=> 0.034 m^3 is the volume of cylinder.

Answer 2

Formula to find volume of a cylinder = πr²h

Circumference = 2πr = 1.32 m

2πr = 132 cm

πr = 66 cm

r = 66/π

Volume = π × ( 66 / π )² × 25

= 25 × 66 × 66 / π

= 25 × 66 × 66 × 7 / 22                ∵ π = 22/7

= 34,650 cm³

to m³ :

34,650 × $10^{-6}$ = 0.034650 m³
