Question

What is the Formula of Cylinder ?​

Answer 1

$\bf\green{\underline{\underline{\fbox{AnsweR:}}}}$

$\bf\purple{\underline{Cylinder: -}}$

A cylinder is a closed solid that has two parallel (usually circular) bases connected by a curved surface.

• A cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance.

$\bf\blue{\underline{Formula: -}}$

$\bf{Lateral\: Surface\:Area- 2πrh}$

$\bf{Total\: Surface\:Area- 2πrh+2πr^2}$

$\bf{Volume- πr^2h}$

$\bf\pink{\underline{Properties\:of\:Cylinder: -}}$

• The bases are always congruent and parallel.

• If axis forms a right angle with the bases, which are exactly over each other, then it is called as “Right Cylinder”.

• It is similar to the prism since it has the same cross-section everywhere.

Answer 2

Step-by-step explanation:

There are 3 formulas of cylinder:

1. LATERAL SURFACE AREA:-

_____________________

2πrh

Where π is 22/7 or 3.14

r is Radius

h is height

2. TOTAL SURFACE AREA:-

_____________________

2πrh + 2πr²

π = 22/7 or 3.14

r = radius

h = height

3. VOLUME:-

__________

πr²h

Where π = 22/7

r = radius

h = height
