The circumference of the circle can be calculated using the following rule:
circumference = 2*pi*radius
We are given that:
circumference = 62.8 ft
pi = 3.14
Substitute with the givens to get the value of the radius as follows:
62.8 = 2*3.14*radius
radius = 10 ft
Now, diameter of a circle is twice its radius, therefore,
diameter = 2*10 = 20 ft
Answer: C
Step-by-step explanation:
Answer:
A relation is not a function if it repeats its input values, or x values.
Step-by-step explanation:
For example, the relation 4,3 3,6 7,5 ,3,8 would not be a function because it repeats the x value of 3 in the points 3,6 and 3,8.
The relation 4,3 3,6 7,5 and 8,3 would be a function because it does not repeat the input values.
Hope this helps!

<h3>What are the equivalent expressions?</h3>
Equivalent expressions are similar expressions that may have different forms but when a value is replaced with the variables in the same form provides the same answer.
From the information given, If:
- r(x) = 3x - 1
- s(x) = 2x + 1
Then the fractional form can be an expression as:
