Use a net to find the surface area of the open cylinder with only one base. Use 3.14 for pi.
Mandarinka [93]

Answer:

251.20 cm square

Step-by-step explanation:

As given in figure

height of cylinder = 2 cm

radius of cylinder = 8 cm

lateral surface area of cylinder is given by = \pi r l

where r is the radius and l is the height

Therefore, lateral surface area of given cylinder

\pi r l = 3.14*8*2 = 50.24

area of base is give by \pi r^2

since there is only one base area of that base

= \pi r^2 = 3.14*8^2 = 3.14*64 = 200.96

Thus,

Total surface area of open cylinder = 50.24 + 200.96 = 251.20 cm square
