Cylinder mensuration tricks with solved math

Cylinder mensuration is also a valuable math chapter for competitive exams. Here we are going to discuss Cylinder properties, Surface area and volume measurement formula and shortcuts tricks. Look at the below images, it is Cylinder and its properties.
The last mensuration tutorial was on Cube and cuboid mensuration tricks. If you have read that's then you can easily adapt to this tutorial. Because, if We make a cylinder into plane figures then we will get two circles and a rectangular figure. These will help you to find the surface area easily. Generally, in question, two types surface area are asking. They are
1.Total surface area of cylinder
2. Curve surface area of the cylinder.

As you have calculated Lateral and total surface area of Cube and Cuboid. Hope, here no introduction need about the Curve and Total Surface area of Cylinder. Let's move to Formulas.

Cylinder Surface area formula

Cylinder Curve Surface area

The formula for the curve surface area without the yellow portion in above image. As you look at the left-hand side of the cylinder a rectangular picture also laid. The area of the rectangular portion is the Curve Surface area of the cylinder. If we know the height of the cylinder and also the radius of top or bottom circle then easily calculation can be done. Because the area of the rectangular is equal to (Circumference X Height).look at below.

Total surface Area

: You have seen the above images, there are a square or rectangular and two circles. Just add all area of three properties. Look at below how the shortcut formula made in a single formula.
Thanks for being here today, hope you have enjoyed the Cylinder mensuration Shortcut formula. For more mensuration chapters, visit the mensuration tricks section.
