Answer:
Cost = $12660.48
Explanation:
Given that,
The height of the cone shape, h = 84 inches
The radius of base, b = 8 inches
The cost per cubic inch is $2.25.
The cost of nickel for the sculpture is given by :
![C = 2.25* (1)/(3)\pi r^2 h\\\\=0.75* 3.14* 8^2* 84\\\\C=\$12660.48](https://img.qammunity.org/2022/formulas/mathematics/high-school/4ljlcj8gjsgtvig2vb83mgmo51o5mu6xe0.png)
