Answer:
1130.97336 units^3
Step-by-step explanation:
The volume of a cylinder can be found using:

We have the area of the base, but not the radius

We know the area is
, so we can substitute that in for a

We want to find r, so we need to isolate it
Divide both sides by pi
36=r^2
Take the square root of both sides
6=r
Now we know the radius, and can substitute it into the volume formula, and we can substitute the height (10) in


Solve the exponent


v=1130.97336
The volume is 1130.97336 units^3

Answer:
B. 0.69
Step-by-step explanation:
Law of Cosines: cos A = (b² + c² - a²) / 2bc
cosθ = (7² + 11² - 8²) / 2*7*11 = 106/154 = 0.688 ≈ 0.69
