Answer:
Given :
Radius of Cylinder is 5 m.
Height of Cylinder is 21 m.
To Find :
Curved Surface Area of Cylinder.
Solution :
\longmapsto\tt{Radius=5m}⟼Radius=5m
\longmapsto\tt{Height=21m}⟼Height=21m
Using Formula :
\longmapsto\tt\boxed{C.S.A\:of\:Cylinder=2\pi{rh}}⟼
C.S.AofCylinder=2πrh
Putting Values :
\longmapsto\tt{2\times\dfrac{22}{{\cancel{7}}}\times{5}\times{{\cancel{21}}}}⟼2×

\longmapsto\tt{2\times{22}\times{5}\times{3}}⟼2×22×5×3
\longmapsto\tt\bf{660{m}^{2}}⟼660m

So , The C.S.A of Cylinder is 660 cm².
_______________________
C.S.A of Cylinder = 2πrh
T.S.A of Cylinder = 2πr(r+h)
Volume of Cylinder = πr²h
