You're standing 14 feet from the edge of a cylindrical water tank and is 26 feet from the point of tangency. the tank is 10 feet tall. what is the volume in cubic feet
The radius of the tank can be found using
26^2 = 14^2 + r^2
r^2 = 480
since the radius is perpendicular to any tangent line.
Now just plug in
v = pi*r^2*h
