Step-by-step explanation:
You use the Distance Formula
d= √( x2 - x1 )^2 + ( y2 - y1 )^2
substitute
r= √(3-3)^2 + (4-1)^2
√0^2 + 3^2
r = √9
r = 3
Now you can use the equation for finding the circumference
2πr
2π3
≈ 6π or 18.85
I think the first is 225 and second is 75 i’m so sorry if this is wrong this is so confusing
Answer:
= 30
Step-by-step explanation:
Well, this could be a "hecto" but in practice it's not really used. If you want to use it, you would speak of "hectometers".
if your question would be 1000 times larger, then it would be "kilo" and this one is actually widely used.
