A 6-meter-high conical mold, sawed vertically along the height into two parts with the same shape and size. The surface area increased by 24 square decimeters. The main body of this mold
The increased area is the area of two triangles, so the diameter of the circle can be found: 24/2 =12; 12/2/6= 1 (decimeter)
Knowing the diameter, it is easy to find out the volume of the cone, according to the formula: v=(3. 14×0.52×6)/3.
V= 1.57
