A rectangular field is 160 ft by 330 ft. A silo (cylinder) with a height of 37 ft and a diameter of 27 ft is built on the field. How much area for planting is left over after the silo is built?
Area of field (Af) = 160×330
= 52800 ft^2
Dia of cylindrical silo (D) = 27ft
Area covered by silo (As)= π/4 × D^2
= π×27^2 ÷ 4
= 572.55 FT^2
Silos are vertical so only circular cross section of silo is cover area in field.
Area left for planting = Af - As
= 52800 - 572.55
= 52227.45 ft^2
