Can someone plz help me with this math problem.
galben [10]
For question one, you would need to use the formula pi r ^2. So first you have 4.5, which is your radius(stands for r). Then you square it, which is 20.25. Then, you multiply 20.25 with pi. Then for circumference, you do 2 x pi x the radius which is 4.5. So for area, you get 63.62. Then for circumference you get 28.27. 

For question 2, it is basically the same steps but instead you a diameter, not a radius. To get the radius, divide by 2, which the radius will be 6. Then from there, the radius is 6, and you solve the question.

Rewrite the equation correctly.
Nataliya [291]

Answer:

<h2>y = 2x - 5</h2>

Step-by-step explanation:

2x - y = 5         <em>subtract 2x from both sides</em>

2x - 2x - y = -2x + 5

-y = -2x + 5          <em>change the signs</em>

y = 2x - 5
