For any circle, the circumfrence C=2\pi r=\pi d where r is the radius and d is the diameter.
Use 20 inches for our radius in the formula C=2\pi r.
C=2\pi \times20
Using π ≈ 3.14...
C\approx2\times3.14\times20
C\approx6.28\times20
\boxed{C\approx125.6\ inches}

 C = pi*d = 2*pi*r
C = 2*pi*20 = 3.14*40 = 125.6in

What Is 1,270 rounded to the nearest hundred?
ankoles [38]
It would be 1,300. When rounding, you'd need to look at the number to the right of the place you're rounding to. In this case, you're rounding to the hundreds place (the 2), so you look at the number to the right (7). To know if you round up or down use this:

Round down= 0-4
Round up= 5-9

Evan’s family drove to a theme park for vacation. Assume they drove the same speed throughout the trip. The first day, they drov
Pepsi [2]
In the given problem the best hint that is given for getting to the answer is that Evan's family drove at the same speed each day.
Then
On the first day the speed of the car = Distance/time
                                                           = 300/6
                                                           = 50 miles/hour
Then for calculating the distance traveled on the third day = speed * time
                                                                                             = 50 * 3
                                                                                             = 150 miles
Then on the third day they arrived at the park by driving 150 miles in 3 hours. So the correct option is option "C".
