This is what I would do.
The general formula for the circumference of a circle is
![2\pi \: r](https://tex.z-dn.net/?f=2%5Cpi%20%5C%3A%20r)
where r is the length of the radius of the circle. Simply use the formula to find r so that you can draw the circle:
![2\pi \: r = 3.14 ^{2} inches \\ r = \frac{3.142 ^{2} }{2\pi} = 1.571 \: inches](https://tex.z-dn.net/?f=2%5Cpi%20%5C%3A%20r%20%3D%203.14%20%5E%7B2%7D%20inches%20%5C%5C%20r%20%3D%20%20%5Cfrac%7B3.142%20%5E%7B2%7D%20%7D%7B2%5Cpi%7D%20%20%20%3D%201.571%20%20%5C%3A%20inches%20)
Now, draw a circle with a radius of 1.571 inches. This number has been rounded up to 3 significant figure. Hope this helps!
Answer:
18
Step-by-step explanation: 24/4=6 so if you multiply one by six you must multiply the other by six to make sure they're to the same scale 3*6=18

Answer: 15 miles</h3>
===========================================
Work Shown:
t = time it takes to go from Jackie's house to her friends house
distance = rate*time
d = 30*t
This represents the distance they travel if they go 30 mph
Then when going back home, they take 6 minutes longer
6 minutes = 6/60 = 0.1 hours
So they take 0.1 hours longer meaning the t updates to t+0.1
d = r*t
d = 25*(t+0.1)
d = 25t+2.5
This represents the trip back home.
Since the distance d doesn't change, we can equate the two right hand sides and solve for t
30t = 25t+2.5
30t-25t = 2.5
5t = 2.5
t = 2.5/5
t = 0.5 hours = 30 minutes
d = 30t = 30*0.5 = 15 miles
