Question

A cylindrical vessels, open at the tob, has
a radiuss 10 cm & height 14cm. Find the total surface
area of the vessel. " Take pi 3.14)​

Answer 1

Answer

1193.2 cm²

Step-by-step explanation:

Total surface Area = 2πrh + πr²

A = 2*3.14*10*14 + 3.14*10^2

A = 1193.2 cm²

Answer 2

Answer:

$given \: = r = 10cm \\ h = 14cm \\ \\ find = tsa \: \\ \\ solution = \\ tsa \: = 2\pi \: rh \: + \pi \: {r}^{2} \\ = 2 \times 3.14 \times 10 \times 14 + 3.14 \times {10}^{2} \\ = 879.2 + 314 \\ = 1193.2 {cm}^{2} \\ \\ hence \: the \: tsa \: of \: the \: cylindrical \: vessel \: = 1193.2 {cm}^{2} \\ \\ the \: formula \: used \: in \: the \: \: answer \: is \: 2\pi \: rh + \pi \: r {}^{2} = tsa \: of \: cylinderal \: \: vessel \:$
