Peak height = Initial height + (Initial velocity * time to peak) - (1/2 * 32 ft/sec/sec * time ^2)
=6 + (37.76*1.18) - (16*1.18 ^2)
=6 + 44.56 - 22.28
=28.28 ft
Spreadsheets are for sissies.

Having not watched the video showing the full trajectory, I assumed that the ball returned to the ground, not to his helmet. In which case, the 2.36 seconds is total time in the air, involving an asymmetric parabolic arc, and more complicated math than that sissy stuff you just posted via cut-and-paste.
Neener neener.
