Hi there, I am not a math person at all and I need a math problem explained step by step in "dummy" terms to me so I can solve similar problems in the future!
Here is my sample problem:
C = πd (d = diameter)
A = πrē (the area of the circle is 9π)
What is the circumference of the circle?
First of all, this isn't a homework question. I'm not in a math class, so I don't have any math homework. This problem is an example from the ACT practice booklet.
I'm taking the ACT test Saturday and I need to know how this type of problem is solved step by step so that I will know how to solve the ones on the ACT test.
What I don't understand is how the problem works or how it is solved, at all. I don't understand ANY of it.
What's the point of a math help forum if the helpers aren't truly willing to help in the way needed?
For the problem solve for r as has been done in post 2 and 4 and then find C.
Between now and Sat there is little you can do to improve your score.One important point - all these tests tend to confuse the taker. For example in this question you are given an equation for C in terms of diameter then give you an area in terms of r so you have to note this after you find r.Can you solve simple equations? And you know about pi ?
