How To Calculate The Surface Area Of A Cylinder Using The Formula: 2Πr(H + R)

Surface area of a Cylinder

Volume of Triangle Prism= (area of triangular base)x(height of prism)

The surface area of a cylinder is the total area of all the external surfaces of the cylinder. It is given by the formula:

Surface area of cylinder = 2πr(h + r)

Where r is the radius of the circular base of the cylinder and h is the height of the cylinder.

To find the surface area of cylinder, we need to first calculate the values of r and h. Once we have these values, we can substitute them in the above formula and calculate the surface area of cylinder.

Example:

Find the surface area of a cylinder with radius 5 cm and height 10 cm.

Solution:

We have:

r = 5 cm
h = 10 cm

Substituting these values in the formula for surface area of cylinder, we get:

Surface area of cylinder = 2πr(h + r)
= 2π(5)(10 + 5)
= 2π(5)(15)
= 150π

Therefore, the surface area of the cylinder is 150π square centimeters.
