Answer:

Step-by-step explanation:
To solve this problem, we can use the area of a circle formula as shown below:

<em>A = area</em>
<em>r = radius</em>
<em />
First we need to find the radius.
The radius is half of the diameter. For this problem, the radius is going to be 3.
Now, plug the values into the equation:


The window's area is 
Answer:
r = -4
Step-by-step explanation:
Step 1: Write out equation
4r + 8 + 5 = -15 - 3r
Step 2: Combine like terms
4r + 13 = -15 - 3r
Step 3: Add 3r to both sides
7r + 13 = -15
Step 4: Subtract 13 on both sides
7r = -28
Step 5: Divide both sides by 7
r = -4
Answer:
Evaluated: 2/3 (or 0.6 repeating) -4 • 9 ÷ -2 ÷ 1/2 (or 0.5)
Equals: 36.6 (.6 is repeating)
