What are the reasons that people say international aid to africa is doing more harm than good? what are some alternatives to sending international aid to african governments? (make sure to answer both questions, should be at least 4-5 sentences)

I think its because most of the people that say that have never been to Africa. And they dont know what they are talking about. If you went to Africa you would understand.

I'm pretty sure there's a geometry rule for   anyways, if the triangle is equilateral, and the circle is circumscribed, the circle is outside of the triangle.  to find the area, you need the radius.  the radius should be a straight line from the center of the triangle to any of it's points.  draw lines from the center of the circle to each of the triangle points.  draw three more lines from the center to the middle of the sides of the triangle.  you should now have six separate 30-60-90 triangles inside of your original triangle. use your 30-60-90 rules to solve for the radius, then the circumference. 

81 is a composite number
