Question

4) if diameter of base is 14cm And
height is 24 cm. find the curved
Surface area Cylinders
aree of​

Answer 1

Answer:

Step-by-step explanation:

Curved surface area of cylinder =2πrh

Given, r=7 cm,

π= 22/7

​ and h=24 cm

Curved surface area of cylinder =2× 22/7*7*24  

=44×24

=1056 cm^2

 

.

Answer 2

Given:-      

• Diameter of the base is 14 cm.
• Height of the cylinder is 24 cm.

To find:-        

• Find the curved surface area of the cylinder.

Solution:-          

Here, we have given that the diameter of the base is 14 cm and the height of the cylinder is 24 cm.

So firstly we will covert the diameter of the base into the radius.

$\qquad\tt{:\implies\:Radius\:=\:\left(\:\dfrac{Diameter}{2}\:\right)}$

$\qquad\tt{:\implies\:Radius\:=\:\left(\:\dfrac{14}{2}\:\right)}$

$\qquad\tt{:\implies\:Radius\:=\:7 \:cm}$

                               ______________

Now we will find out the curved surface area of the cylinder by using the formula.

$\qquad\tt{:\implies\:Curved\:surface\:area_{(\:CYLINDER\:)}\:=\:2\:\pi\:r\:h}$

$\qquad\tt{:\implies\:Curved\:surface\:area_{(\:CYLINDER\:)}\:=\:2\:\times\:\dfrac{22}{7}\:\times\:7\:\times\:24}$

$\qquad\tt{:\implies\:Curved\:surface\:area_{(\:CYLINDER\:)}\:=\:2\:\times\:22\:\times\:24}$

$\qquad\tt{:\implies\:Curved\:surface\:area_{(\:CYLINDER\:)}\:=\:44\:\times\:24}$

$\qquad\tt{:\implies\:Curved\:surface\:area_{(\:CYLINDER\:)}\:=\:1056\:cm^{2}}$

. ° . The curved surface area of the cylinder is 1056 cm²
