Hey there!
Our formula for cylinder area is:
π

h , with r being the radius and h being the height.
When we plug in our values, we get:
A =

A = π(144)(13)
A = 1872π

Therefore, your answer is
B, 1872.Hope this helps!
total angle in a triangle is 180
so the third angle will be 180 - (70 + 40) = 70
angles on a straight line is 180
so x is 180 - 70 ( third angle) = 110
