The formula for the Circumference of a circle is 2 x 3.14 (Pi) x R (or 3.14D).
Our current equation gives us C = 6Pi. This means that we have the diameter.
6 must be our diameter, as we already have Pi.

Since our formula states that we need 2 x R to make D, we must divide the diameter by 2 to get R.

6 / 2 = 3.

Your radius is 3in.

I hope this helps!

Two cars traveling toward each other are 250 miles apart. Car a is traveling 15 miles per hour faster than car

Anon25 [30]

Let car b be travelling at x mph. as they are travelling towards each other their speed of approach is (x + x + 15 ) mph. So we have the equation

speed = distance / time

2x + 15 = 250 / 2

2x = 125 - 15 = 110

x = 55 mph

Car b travels at 55 mph and car a travels at 70 mph Answer
