Answer: B. 26</h3>
============================================
Use law of cosines to find angle A
a^2 = b^2 + c^2 - 2*b*c*cos(A)
9^2 = 6^2 + 14^2 - 2*6*14*cos(A)
81 = 36 + 196 - 168*cos(A)
81 = 232 - 168*cos(A)
81 - 232 = -168*cos(A)
-151 = -168*cos(A)
-168*cos(A) = -151
cos(A) = (-151)/(-168)
cos(A) = 0.8988095
A = arccos(0.8988095)
A = 25.9979801
A = 26 degrees approximately

Answer: 
Step-by-step explanation:
The volume of a cylinder can be calculated with the following formula:

Where "r" is the radius and "h" is the height.
The volume of a sphere can be found with this formula:

Where "r" is the radius.
Then, volume of the empty cylinder is:

And the volume of the ball is:

Finally, you need to subtract them in order to calculate how much water is in the cylinder:

My answer -
The answer is A. about 45 m2
