find the CSA of a cylinder whose radius is 3cm and height is 14
Answers
Answer:
Given :
Radius of Cylinder is 3 cm .
Height of Cylinder is 14 cm .
To Find :
Curved Surface Area of Cylinder .
Solution :
\longmapsto\tt{Radius=3\:cm}⟼Radius=3cm
\longmapsto\tt{Height=14\:cm}⟼Height=14cm
Using Formula :
\longmapsto\tt\boxed{C.S.A\:of\:Cylinder=2\pi{rh}}⟼C.S.AofCylinder=2πrh
Putting Values :
Putting Values :
\longmapsto\tt{2\times\dfrac{22}{{\cancel{7}}}\times{3}\times{{\cancel{14}}}}⟼2×722×3×14
\longmapsto\tt{44\times{3}\times{2}}⟼44×3×2
\longmapsto\tt{44\times{6}}⟼44×6
\longmapsto\tt\bf{264\:{cm}^{2}}⟼264cm2
So , Curved Surface Area of Cylinder is 264 cm² ..
_______________________
Curved Surface Area of Cylinder = 2πrh
Total Surface Area of Cylinder = 2πr(r+h)
Volume of Cylinder = πr²h

Answer:
formula:2πrh
CSA=2*(22/7)*3*14
=44*21
=924
