The formula for circumference is pi(diameter) or 2 x pi x radius. So you have the diameter which is 4.25. Next step you need to do is multiply it with pi which is equal to 3.14. Your equation would be C= 3.14 x 4.25.
Answer:

Step-by-step explanation:
The points on the straight line are (P, 0) and (0, R).
The slope would be

And
, because the y-intercept is at (0, R).
So, the equation of this line would be

Where we multiply the equation by 

Therefore, the equation that represents this line is
