C=3.14 • d
3.14 is pi as a number but it’s non ending :3
D is diameter
C is circumference
Since it said the product of pi and diameter it means d or diameter times pi is c or circumference.
So if
D= i don’t n know maybe 5 find what’s c or te circumference.
So 5 multiplyed by pi or 3.14 is your circumference!
If u need help with the problem please don’t hesitate to ask me! And am purely her to help!!! :3

Answer:
slope is m=2
Step-by-step explanation:
5-(-7/3)=22/3
divided by
8/3-(-1)=11/3
=22/3*3/11=2/1*1/1=2
Answer:
(9.5, 0) is in quadrant I. (-4, 7) is in quadrant II. (-1, -8) is in quadrant III.
Step-by-step explanation:
The negative signs say everything (quite literally). If there are no negative signs, it is in quadrant I. If there is one in the x-axis (the first number in an ordered pair), it is in quadrant II. If there are 2 negative signs, it is in quadrant III, and if there is one in the y-axis (the second number in an ordered pair), it is in quadrant IV.
