Right Circular Cylinder
A right circular cylinder is a cylinder whose base is perpendicular to its sides.
The volume of a right circular cylinder is calculated using the following formula:
V = r2h

The curved surface area of a right circular cylinder is calculated using the following formula:
CSA = 2 rh

The total surface area of a right circular cylinder is calculated using the following formula:
TSA = 2 rh + 2r2

Example: Find the volume of a right circular cylinder which has a height of 28 cm, and the base radius 4 cm. Find also the curved surface area of the cylinder.
Solution: We have,
h = height = 28 cm , r = radius of the base = 4 cm
Volume of the cylinder = r2h cubic cm
= 22/7 x (4)2 x 28 cubic cm = 1408 cubic cm
Curved surface area of the cylinder = 2rh cm2 = 2 x 22/7 x 4 x 28cm = 704 cm2
 
   
As many of you know, Winpossible's online courses use a unique teaching method where an instructor explains the concepts in any given area to you in his/her own voice and handwriting, just like you see your teacher explain things to you on a blackboard in your classroom. All our courses include teacher's instruction, practice questions as well as end-of-lesson quizzes for practice. You can enroll in any of our online courses by clicking here.

The format of Winpossible's online courses is also very suitable for teachers who are using an interactive whiteboard such as Smartboard on Promethean in their classrooms, because the course lessons can be easily displayed on such interactive whiteboards. Volume pricing is available for schools interested in our online courses. For more information, please contact us at educators@winpossible.com.
