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?
Thanks!
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?
The point is to make you sufficiently knowledgeable to solve this problem, and any future ones, for yourself. For us it's far easier to teach this once than it would be to answer each and every question. It's Math Help not Math Answers.
For the problem solve for r as has been done in post 2 and 4 and then find C.
Dear southpaw22,
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 ?
