Question

if theradius of a cylinder is 4cm.
and height is 10cm then total
surface area of cylinder is

​

Answer 1

Answer:

Step-by-step explanation:

Given,

radius = 4cm

height = 10cm

Therefore, A/q

Total surface area of cylinder

= 2πr ( r + h )

= 2 × 22/7 × 4 ( 4 + 10 )

= 352cm^2

Answer 2

GIVEN:-

• $\rm{Radius\:of\:the\:Cylinder=4cm}$

• $\rm{Height\:Of\:the\:Cylinder=10cm}$

TO FIND:-

• Total Surface area of Cylinder

FORMULAE USED:-

• ${\huge{\boxed{\rm{2\pi r{(r+h)}}}}}$

Where,

r = Radius

h= Cylinder.

Now,

$\implies\rm{2\pi r{(r+h)}}$

$\implies\rm{2\times{\dfrac{22}{7}}\times{4}\times{(4+10)}}$

$\implies\rm{2\times{\dfrac{22}{7}}\times{4}\times{14}}$

$\implies\rm{2\times{\dfrac{22}{\cancel{7}}}\times{4}\times{\cancel{14}}}$

$\implies\rm{2\times{22}\times{4}\times{2}}$

$\implies\rm{352sqm^2}$.

Hence, The Total Surface area of Cylinder is 352sqcm²

EXTRA INFORMATION.

• $\rm{Lateral\: Surface\:area\:of\:Cylinder=2\pi rh}$

• $\rm{Volume\:of\:Cylinder=\pi r^2h}$

• $\rm{Volume\:of\:Cone=\pi r^2\dfrac{h}{3}}$.
