Question

a cylindrical vessel, open at the top, has a radius 10 centimetre and height 14 cm. find the total surface area of vessel .( take= 3.14)​

Answer 1

Answer:

radius= 10 cm

height= 14 cm

Step-by-step explanation:

surface area of cyclindrical vessel = 2πrh+πr^2

2×3.14×10×14+3.14×10×10

=1193.2cm^2

Answer 2

$\huge\bf\underline{Question:}$

A cylindrical vessel, open at the top, has a radius 10cm and height 14cm.Find the total surface area of the vessel.

$\huge\bf\underline{Solution:}$

According to the question, the cylindrical vessel is open at the top.Hence,the total surface area of the vessel will be equal to the sum of lateral surface area of the cylinder and the area of one of its base.

Surface Area of Vessel

$\implies CSA\: of \: Cylinder + Area \: of \: its \: base \\ \implies 2\pi \: rh + \pi {r}^{2} \\ \implies 2 \times 3.14 \times 10 \times 14 + 3.14 \times {(10)}^{2} \\ \implies 879.2 + 314 \\ \implies1193.2c {m}^{2}$

Therefore,the total surface area of the vessel is 1193.2$\sf{cm^2}$.
