Start by plotting the y-intercept at (0,1).
From that point, count "up 2, right 1" to get a second point on your graph.
If needed repeat that "up 2, right 1" from that second point to get a third point.
Draw the line that connects these 2 or 3 points.
When rounded off then it comes
382.2-297.3=84.9
Step-by-step explanation:
Formula:
d×3.14=C
or
r×3.14×2=C
d=diameter
r=radius
