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.

Answer:
y=x-4
Step-by-step explanation:
Find the slope of the original line and use the point-slope formula y-y1=m(x-x1) to find the line parallel to 3x-3y=5.
Answer: 1/2
Step-by-step explanation:
Circumference is equal to 2πr. Now, if the circumference itself is equal to pi, then the equation becomes the following:
π = 2πr
Divide both sides by pi:
1 = 2r
Divide both sides by 2:
r = 1/2
