The cost to make this steel cone is $2,543.40.
Step-by-step explanation:
Step 1:
The volume of a cone is determined by multiplying with π, the square of the radius (r²) and height (h). Here we substitute π as 3.14.
The radius of the cone is 9 cm and the height is 10 cm.
The volume of the cone,
So the volume of the cone is 847.8 cubic cm.
Step 2:
If 1 cubic cm costs $3.00, the cost of the given cone is the volume multiplied by the unit cost.
The cost to make the steel cone
The cost to make this steel cone is $2,543.40.
