The formula for the volume of a cylinder is v = πr2h. the volume of a cylinder is three times the volume of a cone with the same radius and height. if the volume of a cone with the same height as a cylinder equals the volume of the cylinder, the equation for the radius of cone r in terms of the radius of cylinder r is

Let R be radius of cylinder and r the radius of cone.
πR^2h = 1/3πr^2h
R^2 = 1/3r^2
r^2 = 3R^2
r = sqrt(3) x R

Angles in a triangle ALWAYS equal 180 degrees, so 180-59-63= final angle (58 degrees) Then just use (Tan,Cos,Sin) with the angles to find the lengths, i can’t answer it as i don’t know what the triangle looks like
