Answer: 
Step-by-step explanation:
Given
Height of rectangle is 
Width is 
The area of the rectangle is given by the multiplication of the height and width

Thus, the area of the rectangle is
.
First Question
circumference = pi * diameter
diameter = circumference/pi = 94.2 in./3.14 = 30 in.
The wheels have a 30-inch diameter.
-----------------------------------------------------------------------
Second question
The area of a circle: area = pi * r^2
radius = diameter/2 = 94.2 in./2 = 47.1 in.
area = pi * r^2 = 3.14 * 47.1 in. * 47.1 in. = 6966 in.^2
Answer: 6966 in.^2
-----------------------------------------------------------------------
Third question
The piece of felt has a width equal to the diameter of the wheel. The length has to be the same as 4 diameters.
4 * 94.2 in. = 376.8 in.
Answer: 376.8 in.
Answer:
C. Scalene triangle
Step-by-step explanation:
What I would do is add all of the angles to 180 and then solve for x.
6x + 10 + 7x + 15x + 2 = 180
28x + 12 = 180
28x = 168
x = 6
Then, plug in 6 for each expression to find each angle
6(6) + 10 = 46
7(6) = 42
15(6) + 2 = 92
Since none of the angles are equal and one of the angles is over 90 degrees, triangle GFH is a scalene triangle
You can set up the relation as a table of ordered pairs.
