Question

curved surface area of right circular cylinder is 4.4m^2 . if the radius of the base of the cylinder is 0.7m,find it's height

Answer 1

Heya !!!!


Radius of cylinder = 0.7 m



Let height of the cylinder be H.



CSA of cylinder = 4.4 m²



2πRH = 4.4


2 × 22/7 × 0.7 × H = 4.4



H = ( 4.4 × 7 ) / ( 2 × 22 × 0.7 )


H = 4.4/4.4 m


H = 1 m


Hence,


Height of cylinder is 1 m.

Let the height of the right circular cylinder be h m.

r=0.7m

Curved surface area = 4.4m²

$\longrightarrow$ 2πrh=4.4

$\longrightarrow$ 2 × $\small\dfrac{22}{7}$ × 0.7 × h = 4.4

$\longrightarrow$ 4.4h = 4.4

$\longrightarrow$ h = 1m

$\small\sf\pink{Hence, \: the \: height \: of the \: right \: circular \: cylinder \: is \: 1m}$
