Question

A cylindrical vessels, open at the top, has
a radius 10 cm height 14cm. Find the total surface
area of the vessel. Take pie= 3.14)​

Answer 1

Solution :

C.S.A of cylinder =

$2\pi \: r \: h$

As one side of the vessel is open and another is closed ,

T.S.A. OF VESSEL ------->

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

$\implies \: 2 \times 3.14 \times 10 \times 14 + 3.14 \times 14 \times 14 \:$

$\implies \: 1494.64 {m}^{2}$
