Answer 1

Answer:

$\large\bigstar \: \mathtt{solution}$

$\sf{radius \: = 10cm}$

$\sf{hieght = 14cm}$

Total surface area of the vessel = C.S area + Area of the base

$\rightarrow\sf{2\pi\: rh + \pi \: {r}^{2} }$

$\rightarrow\sf{\pi \: r(2h + r)}$

$\rightarrow\sf{ \frac{22}{7} \times 10(2 \times 14 + 10)}$

$\rightarrow\sf{ \frac{22}{7} \times 10(28 + 10)}$

$\rightarrow\sf{ \frac{22}{7} \times 10 \times 38 }$

$\rightarrow\sf{3.14 \times 10 \times 38}$

$\sf{ = 1193.2 \: c {m}^{2} }$
