You do 1/3(area of the base)(height) so it’s (1/3)(32^2)(39). 13,311.999999 cubic yards is the answer.
The answer is d 25% of 18,250 = <span>4562.5.

Answer:
<h2>
0.0526ft/min</h2>
Step-by-step explanation:
Since the gravel being dumped is in the shape of a cone, we will use the formula for calculating the volume of a cone.
Volume of a cone V = πr²h/3
<em>If the diameter and the height are equal, then r = h</em>
V = πh²h/3
V = πh³/3
If the gravel is being dumped from a conveyor belt at a rate of 20 ft³/min, then dV/dt = 20ft³/min
Using chain rule to get the expression for dV/dt;
dV/dt = dV/dh * dh/dt
From the formula above, dV/dh = 3πh²/3
dV/dh = πh²
dV/dt = πh²dh/dt
20 = πh²dh/dt
To calculate how fast the height of the pile is increasing when the pile is 11 ft high, we will substitute h = 11 into the resulting expression and solve for dh/dt.
20 = π(11)²dh/dt
20 = 121πdh/dt
dh/dt = 20/121π
dh/dt = 20/380.133
dh/dt = 0.0526ft/min
This means that the height of the pile is increasing at 0.0526ft/min

I can't do the graph but I'm sure you can figure it out!
Hope I helped.
Answer: 1) 530.66 ft^2
Step-by-step explanation:
You need to find the area of the circles.
They gave you the formula to find them which is
Area = Pi * R^2 //// Pi times Radius squared will give you the area.
For example, the radius of the 1st question is 13ft. We use it with the formula given.
A = 3.14 * 13^2 /// 13 squared is just 13 x 13 = 169
A = 3.14 * 169 /// Now multiply Pi times 169
A = 530.66 /// Thats your answer.
530.66 ft^2
