A metal alloy consists of 75% copper and 25% zinc. If 2.5 kg of the alloy is melted and cast into a cylindrical shape, what is the volume of the cylinder?

A. \( 2.5 , \text{kg} \times 0.75 \times 8.9 , \text{g/cm}^3 \)

B. \( 2.5 , \text{kg} \times 0.75 \times 8.9 , \text{g/cm}^3 \times 1000 , \text{cm}^3/\text{L} \)

Correct Answer C. \( 2.5 , \text{kg} \times 0.75 \times 8.9 , \text{g/cm}^3 \times 1000 , \text{cm}^3/\text{L} \times pi , \text{r}^2 \)

D. \( 2.5 , \text{kg} \times 0.75 \times 8.9 , \text{g/cm}^3 \times 1000 , \text{cm}^3/\text{L} \times pi , \text{r}^2 \times 2 , \text{cm} \)
