Volume of a cylinder = π · radius(r)² · height(h)
Since you didn't provide the radius or the height, I am unable to provide a solution to this problem but hopefully you can solve it on your own now that you have the formula.
They are equal. 0.1x58=5.8, 5+0.8=5.8
The answer to this is C.54 units² .
Area=1/2 base*height
base=12
height=9
12*9=108
108/2=54
Area=54
The simplification for this equation would be, 4x^2 y^26
The correct answer is B. $210
