Answer:
The area of a circle with a diameter of 10 inches is 78.5 in².
Step-by-step explanation:
1. Know the formula for finding the area of a circle.
A = r²
2. Since you need the radius for finding area, you will need to divide 10 by 2 because the radius is half of the diameter.
10 ÷ 2 = 5
3. Add in your numbers to the formula.
A = (5)²
4. Simplify the equation. We can use 3.14 for pi.
A = 25
A = 78.5
So, the area of the circle is 78.5 in².
<h3>
Answer: Choice A</h3>
Explanation:
Notice how the input 5 leads to the output 3 when we look at the S(x) function. The inverse will undo this. So that must mean the answer is choice A where we have the input 3 lead to the output 5. In short, the inputs and outputs swap places. This means the domain and ranges swap.
I thinks it’s between A and B

Answer:
Approximately 4.67 feet of fabric is required for one pillow case.
Step-by-step explanation:
We are given the following in the question:
Number of pillow cases to be made by Jenny = 3
Amount of fabric Jenny has = 14 feet
Each pillow case use same amount of fabric.
Amount of fabric used to make 1 pillow case =
Thus, approximately 4.67 feet of fabric is required for one pillow case.
