Question

A cylindrical vessel open at the top , has a radius 10 cm and height 14 cm . find the t.s.a of the vessel ? ​

Answer 1

Answer:

Here we will find the sum of the curved surface area of the cylindrical vessel and the area of the base of the cylindrical vessel using the formula. After calculating all these, we will get the required value of the total surface area of the vessel. A cylinder is a three-dimensional geometrical figure or structure that has two circular bases which are parallel to each other and are at some distance apart.

Formula used:

Total surface area of the cylinder open at the top =2πrh+πr2

, where h

is the height of the cylinder and r

is the radius of the cylinder.

Complete step by step solution:

Here we need to find the value of the total surface area of the vessel which is cylindrical in shape.

It is given that the radius of the cylindrical vessel is equal to 10 cm and height of the cylindrical vessel is equal to 14 cm.

We will first draw the figure of the cylindrical vessel.

Now, we will calculate the total surface area of the cylindrical vessel which is equal to the sum of the curved surface area of the cylindrical vessel and the area of the base of the cylindrical vessel.

Total surface area of the cylindrical vessel =2πrh+πr2

Now, we will substitute the value of the radius and the height of the cylindrical vessel.

⇒

Total surface area of the cylindrical vessel =2×3.14×10×14+3.14×10×10

On multiplying the numbers, we get

⇒

Total surface area of the cylindrical vessel =879.2+314

Adding the terms, we get

⇒

Total surface area of the cylindrical vessel =1193.2cm2

Hence, the total surface area of the cylindrical vessel is equal to 1193.2cm2
