<em><u>In mathematics, a cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance. These bases are normally circular in shape (like a circle) and the center of the two bases are joined by a line segment, which is called the axis</u></em>
The answer would be 28 square inches because you would multiple the length (4 inches) and the width (7 inches) to each other.
Answer:
x= 4.5
Step-by-step explanation:
90-36=54
54 divided 12 = 4.5
Your answer would be A) a+c+e
a-b+c
b-c+d
c-d+e
+
——————
a+c+e
Let x represent the length in feet of the area along the barn wall. Then the width of the area (out from the wall) will be 450/x, and the total cost of fence will be
cost = 5*(x +2*450/x)
A graphing calculator shows the minimum of the cost function is where x=30.
In order to minimize the cost of fencing, the fourth side should be 30 ft long.
