Answer:
[tex]T = 1300[/tex]
Step-by-step explanation:
Given
[tex]Radius, r = 9\ in[/tex]
[tex]Height, h = 14\ in[/tex]
See attachment
Required
Determine the total surface area, T
T is calculated using:
[tex]T = 2\pi r(r + h)[/tex]
Substitute values for r and h
[tex]T = 2\pi * 9(9 + 14)[/tex]
[tex]T = 2\pi * 9(23)[/tex]
Remove bracket
[tex]T = 2\pi * 9*23[/tex]
[tex]T = 2\pi * 207[/tex]
Take [tex]\pi = 3.14[/tex]
So, we have:
[tex]T = 2 * 3.14 * 207[/tex]
[tex]T = 1299.96[/tex]
[tex]T = 1300[/tex] --- approximated.
Hence, the surface area is 1300 square inch
