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 in³.
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
Answer:1.8
Step-by-step explanation:
1298 - 4x =171 + 3x
Add 4x to both sides
1298 = 171 + 7x
Subtract 171 from both sides
1127 = 7x
Divide by 7 on both sides
x = 161
They will both say the number 161 at the same time.
3x - 6y = -2
-6y = -3x - 2, divide through by -1
6y = 3x + 2, divide through by 6
y = 3x/6 + 2/6
y = x/2 + 1/3
