Answer:
3 dollars and 60 cents
Step-by-step explanation:
The answer to the question is a. The formula for finding the area of a circle is
![A= \pi r^2 ](https://tex.z-dn.net/?f=A%3D%20%5Cpi%20r%5E2%0A)
. So, The radius is 6. So, You can now do 6 to the power of 2 getting you an answer of 36 times pi=area. Now, For the area of the rectangle do length times the width which is 12 times 18 gets you 216. Then, the equation to get you your answer should be 216-36pi. NOT SO FAST almost forgot about the circle being half so divide the 36 and you get 18. So, the answer is ACTUALLY D. 216-18pi.
Confused a bit, can you make sure you copy and pasted it right?
This might have your answer, I'm so sorry if I'm wrong.
A = 18
You need to
Multiply both sides of the equation
- 3/2 x (-2/3) x a = - 3/2 x - 12
Then simplify both sides
a = - 3/2 x 12
Simplify
-3/2 x -12
a = -3 x -6
Multiply -3 by -6
Answer: a = 18
