The formula to calculate the area of a circle is π*r^2, where r is the radius and pi is 3.14159265358979......

With that said, we could calculate the area of the outer red ring, but we just know the diameter. Since the radius is half the length of the diameter, the area of the ring will be 25π - (8/2)^2π , since the red ring is the different of the two circles.

Using the same logic, the red ring smaller than that is 5π, and the red circle in the middle is 1π. Adding those numbers together, we will get

9π + 5π + π 

The answer to this problem is 15π. 

I hope this helped,

This question is impossible to answer, because we have no relation between the number of weeks and the number of candy bars sold. We could sell one in 30 weeks are 100 in 1 week, if you can post the original question, I would glady do it. 

Thanks,

Thanks CPhill

Triangle CHS is similar to triangle triangle TFY

Assuming you mean 25%, the answer will be 25/100 * 12, which is 3.
