Answer:
c = $0.8
Step-by-step explanation:
Let
cost of material = c
Diameter = d
c = k*d²
If it costs the manufacturer $0.45 for the material of a Frisbee with a 9-inch diameter
c = k*d²
0.45 = k * 9²
0.45 = k * 81
0.45 = 81k
k = 0.45/81
k = 0.0055555555555
what is the cost for the material for a Frisbee with a 12-inch diameter
c = k*d²
c = 0.0055555555555 * 12²
c = 0.0055555555555 * 144
c = $0.8
50/25=.5
.5*90= 45
