Question

find the total surface area of the cylinder who's diameter is 2cm height is 3cm

Answer 1

The two circles that make up the ends of the cylinder.The side of the cylinder, which when "unrolled" is a rectangleCombining these parts we get the formula:

where:
π  is Pi, approximately 3.142
r  is the radius of the cylinder
h  height of the cylinder

For a detailed look at how this formula is derived, see Derivation of the surface area of a cylinder.

Units

Remember that the radius and the height must be in the same units - convert them if necessary. The resulting area will be in those square units. So, for example if the height and radius are both in centimeters, then the area will be in square centimeters.

Answer 2

Question: find the total surface area of the cylinder who's diameter is 2cm height is 3cm ?

Method of Solution:↪

➡ Given:

↪ Diameter of Cylinder = 2 Cm

↩↪ Radius of Cylinder = 1 Cm

➡ To Find : TSA of Cylinder


↪ Total Surface Area Of Cylinder = 2πr(h+r)

↪ Total Surface Area Of Cylinder = 44/7×1 (1+3)

↪Total Surface Area Of Cylinder = 44/7×4

↪Total Surface Area Of Cylinder = 25.14 Cm²


Hence, Required Total Surface Area Of Cylinder is (25.14 cm²)↩↩↩.
