Answer:
4561.6 units squared
Explanation:
The volume of a cylinder is defined by this equation: πr2h
r = radius = 11 units
h = height = 12 units
π = pi = 3.14152...etc. (In your case, just use 3.14)
So you plug these into the equation:
πr2h = (3.14) x (12) x (11^2)
Here, we will write squared as a number ^2, meaning that you multiply that number by itself twice.
Since 11 x 11 = 121, we can now solve for the volume:
(3.14) x (12) x (121) = 4561.6 units^2
