Hwlp its easy. a cylinder has a height of 1.2 cm and the following base. what is the surface area of the cylinder in square

194.68

Step-by-step explanation:

Surface area of a cylinder

Definition: The number of square units it takes to exactly cover the surface of a cylinder. Given by the formula:

area=2π  r2  +2πrh  

where:

π  is Pi, approximately 3.142

r  is the radius of the cylinder

h  height of the cylinder

Try this Drag the orange dot to resize the cylinder, note how the area is calculated.

The surface area of a cylinder can be found by breaking it down into three parts:

The two circles that make up the ends of the cylinder.

The side of the cylinder, which when "unrolled" is a rectangle

Combining these parts we get the formula:

area=2π  r2  +2πrh  

where:

π  is Pi, approximately 3.142

r  is the radius of the cylinder

h  height of the cylinder

Surface area of cylinder = 533. 8 square mm.

Step-by-step explanation:

Given  : A cylinder with height = 1.2 cm , radius =  5 mm.

To find : What is the surface area of the cylinder in square millimeters.

Solution : We have given  cylinder with height = 1.2 cm , radius =  5 mm.

1 cm = 10 mm

So ,

Height 1.2 cm = 12 mm.

Surface area of cylinder = 2 * pi ( radius + height ) .

Plug the values pi = 3.14 , radius = 5 mm ,  height = 12 mm.

Surface area of cylinder = 2 * 3.14 ( 5 + 12 ) .

Surface area of cylinder = 2 *3.14 ( 17 ) .

Surface area of cylinder = 533. 8 square mm.

Therefore, Surface area of cylinder = 533. 8 square mm.
