A sculpture is made of solid copper in the shape of a cone. The sculpture is 67 inches tall, and its base has a radius of 15 inches. If copper costs $1.06 per cubic inch, how much did the copper for the sculpture cost?
+37084 Volume of a cone is given by pi r^2 h/3
V = pi x 15^2 x 67/3 = 15786.5 in^3
$1.06/in^3 x 15786.5 in^3 = $ 16,733.69
