pi is the ratio of circumference to the diameter of same circle. The length of the metal frame of trampoline considered is: Option D: 37. 7 feet.
<h3>How to find the length of the outer line of a circle?</h3>Length of the outer line of a circle is called its circumference.
If the circle has got radius of r units length, then
Circumference of that circle = 2π r units = πd units where d is diameter of that circle.
This is why, we get the ratio of circumference to diameter as:
It is given that the trampoline in consideration has got diameter of 12 feet.
It is said that π = 3.14 to be considered (its not its exact value though).
Therefore, we get
Hence, the length of the metal frame of trampoline considered is obtained as: Option D: 37. 7 feet.

Answer:
The expression has two variables x and y.
Step-by-step explanation:
<u>What is a variable?</u>
A variable is a letter, for instance or
, that represents an unknown number.
Given the expression
The given expression has three terms which are x, 4y, and -9.
Here:
- The term 'x' is the unknown variable x.
- The term '4y' has a coefficient (the number next to a variable y) of 4.
- The term '-6' is a constant.
As we already know that a variable is a letter, for instance x or y, that represents an unknown number. In other words, the values of x, or y are unknown to us.
Thus, the expression has two variables x and y.
