Answer 1

Answer:

69.08 ${m}^{2}$

Step-by-step explanation:

Given,

Radius ( r ) = 1 m

Height (h) = 10 m

Surface area of cylinder= ?

Now,

Surface area of cylinder :

$2\pi \: {r}^{2} + 2\pi \: r \: h$

$= 2\pi \: r \: (r + h)$

$= 2\pi \: \times 1(1 + 10)$

$= 2\pi \: \times 1 \: \times 11$

$= 22\pi$

$= 22 \: \times 3.14$

$= 69.08 \: {m}^{2}$

Hope this helps...

Good luck on your assignment..
