16π in²

Step-by-step explanation:

Step 1:

We know that area of circle is given by

           A=π * R²  units

Where A= Area

           R= Radius = (Diameter/2)

Step 2:

Here r= 4 inches

Area =  \pi * 4 *4

         = 16\pi in²

The answer is 50.24. First, take the diameter and divide it by two (4). Then, multiply it by itself (16). Lastly, multiply it by pi,(3.14).

Part A

So the coefficient would be the number that is with a variable. The coefficient of 7.50h is 7.50. The variable is h, variables can be a letter or symbol that stands for something in a equation. For this question, h stands for the number of hours Corinne works. The constant is the number that is alone in the equation. That doesn't have a variable with it. In this equation the constant would be the number 40.


Part B

To solve this I will plug in 25 into "h" in and 300 for "s" in the equation 7.50h + 0.20s + 40 and then solve.


1. 25 * 7.50 = $187.5.

2. 0.20 * 300 = $60

3. Add it all together: $187.50 + $60 = $247.50 + $40 = $287.50


Part C

If Corrine gets a raise and earns $9 an hour the coefficient would change. It would be 9h instead of 7.50h.

Help Me Number 6 or if you can help me with number 7 if you want too ☺️
Makovka662 [10]
Simply use the formula they give you. For question 6, 4 is the radius. So the area of the circle is 4pi. Now for seven you do the same thing, but they gave you the diameter instead and it’s a half circle. So try that one on your own. Let me know if you get stuck
