Question

Total surface area of a cyclinder of definition in maths simple words

Answer 1

Answer:

I hope this will help you mate.......

To find the surface area of a cylinder add the surface area of each end plus the surface area of the side. ... There are two ends so their combinded surface area is 2 π * r2. The surface area of the side is the circumference times the height or 2 π * r * h, where r is the radius and h is the height of the side.

Answer 2

Answer:

The cylinder's surface area is 2πr² + 2πrh

Step-by-step explanation:

Surface Area of Cylinder:-

Firstly, determine each length of the cylinder and add each surface area of the end. And each end of a cylinder is a circle which is equal to π×r² and there are two circles in the cylinder.

Where,

• r = radius of the end circle.

The surface area of the side is the circumference times the height or 2π×r×h.  

where,

• r is the radius  
• h is the height of the side.

Hence, the cylinder's surface area is 2πr² + 2πrh
