Step-by-step explanation: i would right an explanation but i cant put it all so you will just have to trust me
An equation in point-slope form is
y - y1 = m (x - x1)
Your point is (7,6) and your slope is 2
y1 is the y coordinate of your point (in this case 6)
x1 is the x coordinate of your point (in this case 7)
m is your slope (in this case 2)
Now you just have to plug these numbers in:
y - 6 = 2 (x - 7)
Answer:
if area is given than use formula=πd²/4
if circumference=πd
You could use a ruler, think about how you want the polygon inside of the circle or how you want the circle to surround the polygon. When you use a ruler, make sure your co-ordinates inside of the circle are correct though before drawing the line.
I hope this info helps! :3
