Question

find the csa of cylinder with radius 5 cm and height 14 cm​

Answer 1

Given, r = 5 cm

h = 14 cm

C.S.A = 2πrh

$= 2 \times \frac{22}{7} \times 5 \times 14 \\ = 2 \times 22 \times 5 \times 7 \\ = 44 \times 35 \\ = 1540$

C.S.A of the cylinder is 1540

Answer 2

Answer:

Step-by-step explanation:

Concept:

A cylinder is a three-dimensional solid with a parallel circular base and top. The overall height of the cylinder is the perpendicular distance between the top and base.

Area of a Cylinder: The area of a cylinder is the area that a cylindrical object occupies. There are two sorts of this area

The term "curved surface area" refers to the region that only consists of curved surfaces, leaving the circular top and base.

Given:

The  cylinder  radius $5 cm$ and height $14 cm$

Find:

To find the curved surface area of cylinder

Solution:

Formula for calculating the Curved Surface Area

Consider a cylinder having a height ‘h’ and base radius ‘r’.

The curved surface area of a cylinder is given as

$C.S.A = 2\pi rh$

Given the radius of a cylinder = $5 cm$

Given the height of a cylinder = $14 cm$

C.S.A of the given cylinder $= 2*22/7*5*14$

                                            $= 2*22*5*2$

                                            $= 440 cm^{2}$

Hence the Curved Surface Area of a cylinder is $440 cm^{2}$.
