What is the longest line segment that can be drawn through the interior of this cylinder? r=4ft and h=3ft? Shape is a cylinder

This seems tougher than it really is


The longest segment will be the hypotenuse of a right triangle with legs of 3 ft and  twice the radius =  8 ft....so....letting S be the segment length, we have that.....


S^2  =  3^2  +  8^2


S^2  =  9 +   64


S^2   = 73       take the positive square root of both sides


S  = √73 ft  ⇒  8.54 ft




cool cool cool
