please forgive me, because i haven't done this in quite some time. any help is appreciated. i'm trying to calculate the volume of material that was shaved off a solid cylindrical temperature thermowell. looking from the side, a triangular portion was cut off at an angle from the top down. knowns: the diameter of the cylinder is 1.1 cm the height of the cylinder is 0.8 cm looking top down at the cylinder, perpendicular to the measured diameter, the circle is cut 0.4 cm from the side of the cylinder, leaving the remaining 0.7 cm intact. the cut was at such an angle (approx 63 deg by my calcs) that it exited the thermowell 0.8 cm down from the top. what is the missing volume? as mentioned before, any help is appreciated... thanks!
