The equation for circumference is: 2 x Pi x r

You used the diameter (9), rather than the radius. The radius is the diameter divided by 2. Therefore, your equation should be: 2 x 3.142 x 4.5, NOT 2 x 3.142 x 9.

This means your answer should be 28.3. Hope this helps! Just a minor mistake (:

The formula for circumference is 2 $\pi$ r, where r is equal to radius.
It states to use 3.142 for pi
It also provides you with the diameter, not the radius, so you have to divide it by two to get 4.5
2*3.142*4.5= approximately 28.278 or 28.3

Fynjy0 [20]

The correct answer is C) 900

To begin with, you need to divide the number of days in a year with the number of dogs. When you do this, you multiply it by 50 to get the final answer. In this case, it would be 365 / 20 which when multiplied by 50 gives the number of C) 900 since it's "about" 20 days.
