I’m not sure but I hope this helps
Answer:
x = 58/3
Step-by-step explanation:
We can use cross products to solve this problem
6 7
---------- = -----------
14 x-3
6 * (x-3) = 7 * 14
Divide each side by 6
6 /6* (x-3) = 7 * 14/6
x-3 = 98/6
Add 3 to each side
x-3+3 = 98/6 +3
x = 98/6 +18/6
x = 116/6
Divide the top and bottom by 2
x =58/3
So, these are actually pretty simple once you learn the equality used to solve for "x" and when to implement this method. You can use this equality to solve for a segment "x" anytime that two secant lines cutting through a circle come from the same point outside the circle.
Secant: by geometric definition is just a straight line that cuts a curve into multiple pieces.
I did one of them for you hopefully you can use my work for "a" to help you solve for "b".
For a. I got x=7.
C = pi x d
So the border is about 3.1 x 20 = 62 inches
