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

So, the required cost is equal to $12660.48.
