Guys I'm on my last attempt

Answer:
Step-by-step explanation:
Volume of the cylinder =
pi r^2 h = pi * (12.9)^2 * 660 = 345043 cm^3
Now find the mass of the cylinder
Volume * density = mass
345043 cm^3 * 5.6 g/cm^3 = 1932240.834 GRAMS
this is 1932.240 kg
Now multiply kg mass * price per kg
1932.240 kg * $ .88/kg = $1700.37
