Answer:
$3419.46
Step-by-step explanation:
First we need to find the volume of the cone using the formula for a cone.
h = height = 60 in
r = radius = 11 in
V = (hπr²)/3
V = (60*3.14*11²)/3
V = (60*3.14*121)/3
V = 22796.4/3
V = 7598.8
The volume of the cone is 7598.8 inÂł.
Now, we need to find the cost of the metal by multiplying the number of cubic inches we need by the cost per cubic inch.
cost = .45 * 7598.8
cost = 3419.46
The cost for the steel of the sculpture would be $3419.46
