Let the length of the radius = r feet.
Diameter = 2r = 2 x 6.8 = 13.6 feet
Circumference = 2
r = 2 x 3.14 x 6.8 = 42.704 feet = approx. 42.7 feet
<em>The</em><em> </em><em>diameter</em><em> </em><em>is</em><em> </em><em>1</em><em>3</em><em>.</em><em>6</em><em>0</em><em> </em><em>feet</em><em>.</em>
<em>The</em><em> </em><em>circumstance</em><em> </em><em>is</em><em> </em><em>approximately</em><em> </em><em>4</em><em>2</em><em>.</em><em>7</em><em>0</em><em> </em><em>feet</em><em>.</em>

Answer:
x + y = 4 Equation 1
y = 2x -1 Equation 2
-2x + y = -1
x + y = 4
Subtract
You will get
- 3x = -5
Divide by -3
-3x / -3 = - 5 /-3
x = 5/3
Substitute x into equation 1
x + y = 4
x = 5/3
5/3 + y = 4
y = 4 - 5/3
y = 7/3
x = 5/3 y = 7/3
Hope this helps.
