Question

Find the total surface area of a cylinder in which radius is 15 cm and height is 35 cm​

Answer 1

2 ×22/7 ×Radius× height now put the values and solve

Answer 2

$\star\sf\pink{Given :}$

• Radius of cylinder = 15 cm
• Height of cylinder = 35 cm

$\star\sf\pink{To \ find :}$

• The total surface area of cylinder.

$\star\sf\pink{Solution :}$

We know that ,

$\star{\underline{\boxed{\sf{Total \ surface \ area_{(cylinder)}=2\pi{r}(r+h)}}}}$

According to Question,

$\leadsto\sf{T.S.A._{(cylinder)}=}2\times\dfrac{22}{7}\times15(15+35)$

${\leadsto{\sf{T.S.A._{(cylinder)}=}\dfrac{44}{7}\times15(15+35)}}$

${\leadsto{\sf{T.S.A._{(cylinder)}=}\dfrac{44}{7}\times15(50)}}$

$\leadsto\sf{T.S.A._{(cylinder)}=}\dfrac{44}{7}\times15\times50$

$\leadsto\sf{T.S.A._{(cylinder)}=}\dfrac{44\times15\times50}{7}$

$\leadsto\sf{T.S.A._{(cylinder)}=}\dfrac{33,000}{7}$

$\leadsto\sf{T.S.A._{(cylinder)}=4714.28 cm^2}$

Thus,

${\underline{\sf{Total \ surface \ area \ of \ cylinder \ is \ 4714.28 cm^2}}}$
