Question

Find the curved surface area of a cylinder whose radius is 5cm and height is 10cm

Answer 1

Answer:

the curved suraface area is 314.2857 cm²

Step-by-step explanation:

curved surface area of cylinder = 2πrh

                                                    =2×22/7  ×5×10

                                                    =314.2857cm²

Answer 2

Given :

• Radius of Cylinder = 5cm
• Height of Cylinder = 10cm

To Find :

• Curved Surface Area of Cylinder

Solution :

$\implies\sf{Radius=5cm}$

$\implies\sf{Height=10cm}$

Using Formula :

$\implies\sf\boxed{C.S.A\:of\:Cylinder=2\pi{rh}}$

Putting Values :

$\implies\sf{2\times\dfrac{22}{7}\times{5}\times{10}}$

$\implies\sf{\cancel\dfrac{2200}{7}}$

$\implies\sf\bold{314.2{cm}^{2}}$

So , The C.S.A of Cylinder is 314.2cm²...

_____________________

• C.S.A of Cylinder = 2πrh
• T.S.A of Cylinder = 2πr(r+h)
• Volume of Cylinder = πr²h
