Answer:
area of the circle = 3.14 square units
Step-by-step explanation:
Circumference of the circle formula is 
where r is the radius of the circle
given circumference = 6.28
= 6.28
Value of pi is 3.14
2*3.14 * r= 6.28
6.28 r = 6.28
divide by 6.28 on both sides
r = 1
radius = 1
Area of the circle = 
= 3.14 *1*1 = 3.14
I believe that the answer is 2.
<u>Answer:</u>
An equation that relates the speeds of the two legs of the trip

<u>Explanation:</u>
Given, we have to use x to represent the speed on the second leg
Speed on first leg when increasing your speed by 40 mph will be (x-40)
Distance is given as 640 miles and time is calculated as

According to the question, increasing speed saved four hours
Therefore, the equation that relates the speeds of the two legs of the trip will be

Answer:
1 or 2
Step-by-step explanation:
If you want it equally then it would be 1. The reason for this is cause you will have to divide 3 and 2 by 75 to get 25 and 37. So only 1 can go into both numbers equally. If you want a little bit over you would get 2 cause you would do the same steps like for 1 but you would subtract the 37 and 25 to get the remainder of 12 so it would be 12
The answer you are looking for is 2!!
