Calculate the apothem, perimeter and area of a regular hexagon inscribed in a circle with a radius of 4 cm. P = 6 Â· 4 = 24 cm. The area of a square is 2,304 cmÂ². Calculate the area of a regular hexagon that has the same perimeter as this square.
A crane is a type of machine, generally equipped with a hoist rope, wire ropes or chains, and sheaves, that can be used both to lift and lower materials and to move them horizontally.
This type of crane consists of a pivoting head and boom assembly, which carries a hoist and trolley unit. The pivoting head is supported either by a floor-mounted mast providing 360Â°-boom rotation or by an existing building column, which provides 180Â° of boom rotation.
