Answer:
288π
Step-by-step explanation:
The equation for the volume of a cylinder is V=πr²h
So, To do this you would plug in the values that are given.
The radius would be 4 because it is half the diameter.
And the height is 18
So V=π(4)²(18)
So you just multiply the numbers and not the pi to get 288π
Since 41 is greater than the sum of the other two sides this is not a triangle.
The pasture is in the shape of a rectangle only the widths are marked.
a. Let x be the width of the pasture as labeled. Write an expression for the length in terms of x.
b. Write an expression for the area of the pasture in terms of x.
(a) the hedge along the length . we need to consider the three sides for fencing.
To find the length we use the given information
Dennis plans to use 1150 ft of fence to enclose a rectangular pasture.
Perimeter of rectangle = 2L + 2W
the hedge along the length, so we perimeter becomes L + 2W
Perimeter = L +2W, Width is x and perimeter is 1150
1150 = L + 2x ( subtract 2x on both sides)
So length L = 1150 - 2x
(b)Area of rectangle = length * width
We got L = 1150 -2x and we know width is x
Area = (1150-2x)*x
square feet
y=3,000(0.92)^x

Answer:
$990 per unit.
Step-by-step explanation:
The Unit Cost (C) and Unit Revenue R from the production and sale of x units are related by the function:
We are required to find the rate of change of revenue per unit when the cost per unit is changing by $9 and the revenue is $1,000.
Rate of Change of C,
The Revenue is changing at a rate of $990 per unit.
