Answer:
177.475
Step-by-step explanation:
Since the formula for finding the area of a <u>full</u> circle is A = π, area equals pi times radius squared, we fill out the formula and solve.
A: unknown
Pi: 3.14
Radius: diameter is 12, so you divide it by 2, which is 6.
A = 3.14 x 6 squared.
using pemdas, you do exponents first,
A = 3.14 x 36
A ≈ 113.04
Now that we have the area for the full circle, we divide it by two to find the area of the semicircle,
113.04/2
= 56.52
So, the area of the semicircle is 56.52

1. If Sheryl works 6.5 hours in a day, she makes approximately 85 currency.
2A. If Sherly had not worked for a single hour, she would get no money.
If she worked for 1 hour, here wage would approximately be equal to 13 currency.
If Sheryl works 9 hours she will make approximately 117 currency.
Step-by-step explanation:
Step 1:
To calculate how much Sheryl makes if she works 6.5 hours a day, we check the graph to see what the y value of the graph is when .
When , the line falls on
So if Sheryl works 6.5 hours in a day, she makes approximately 85 currency.
Step 2:
The two points on the graph are at (0, 0) and (1, 13).
This means that if Sherly had not worked for a single hour, she would get no money.
If she worked for 1 hour, here wage would approximately be equal to 13 currency.
These two statements explain the two points on the graph.
Step 3:
To calculate how much Sheryl makes if she works 9 hours, we must create an equation that represents how much money she makes.
If she earns approximately 13 currency an hour, her wage is , where x is the number of hours worked and y is the wage.
When ,
So if Sheryl works 9 hours she will make approximately 117 currency.
