The second bubble is the correct answer i believe...
Answer:
Circumference: 43.9822971503 or 43.98
Area: 153.9380400259 or 153.94
Step-by-step explanation:
So basically for the circumference you use C= d×π which means that the circumference is equal to the diameter (radius times 2) multiplied by pi! For the area you use the formula A= r^2×π which means the radius squared (radius times itself) multiplied by pi! By the way you can also round pi down to 3.14 to make it easier. Anyway I hope this helps!!
Get two points and do change in y over change in x
for example
the 2 points are (2,4) (4,8)
change in y: 8-4= 4
change in x: 4-2=2
4/2= 2
Sorry this took a while but it should be the last option for it to be correct.
