Find the total surface area of a cylinder with a height of 5 cm and radius of 2 cm. leave your answer in terms of π. 28π cm2 24π
AleksandrR [38]

The total surface area of a cylinder with 5cm height and radius 2cm is :

28π cm²

<h3>What is cylinder?</h3>

One of the most fundamental curvilinear geometric shapes, the cylinder has historically been thought of as a three-dimensional solid. Geometrically speaking, it has been referred to as a circle-based prism.

Analysis:

The total surface area of a cylinder is :  2πrh + 2π

where radius  = 2cm , Hight = 5cm

Total surface area = 2 x π x 2 x 5 + 2 x π x 2 x 2

                             = 20π + 8π = 28π cm2

In conclusion, the total surface area of the cylinder is 28π cm2.

I need to know how to divide this fraction
kicyunya [14]
These are not division problems...." the product " means multiply

5 3/4 * 3/2 .....turn mixed number into improper fraction, then multiply
23/4 * 3/2 = 
(24 * 3) / (4 * 2) =
72/8 which equals 9 <==

1/3 * 1/4 =
(1 * 1) / (3 * 4) =
1/12 <==
