Step-by-step explanation:
The surface area of a cylinder is calculated using:
[tex]S.A=2\pi r(r+h)[/tex]
Given that the radius of the cylinder is r =7 units and the height of the cylinder is 3 units, and π=3.14
Then we substitute to obtain.
[tex]S.A=2 \times 3.14 \times 7(7+3)[/tex]
We simplify to get:
[tex]S.A=14 \times 3.14 \times 10[/tex]
We multiply out to obtain:
[tex]S.A=2 \times 31.4[/tex]
We finally get:
[tex]S.A=62.8[/tex]
Therefore the surface area is 62.8 square units
