This is volume of a sphere.
Ok. because those two angles are sumplimentary, (they equal 180 degrees) we can set up an equations.
3n+n+14=180
then isolate the variable
4n+14=180
-14 -14
4n=166
then divide to undo the multiplication
4n=166

Answer:
26.8
Step-by-step explanation:
x/145 = 18.5/100
cross-multiply:
