Question : I'm doing my math homework and the question asks me to use the formula to calculate the area. I've calculated the area but isn't there a sign like squared or cubed that you have to put after it? If so, what is it? Is it squared or cubed?
Thanks! Ok. So that helps me a lot. I have another question now. The next question is:
Use the formula A=bh (divided) 2
So that would mean the value of b multiplied by the value of h divided in half. So I know the answer to the question but do I still have to..
Answer : Area is usually done in 2 dimensions (such as length x width for a rectangle). So, you would have to multiply out your units. For example, the area of a rectangle which is 2 in long and 5 in wide: area = length x width area = 2 in. x 5 in. area = 2*5 in.*in. area = 10 in.^2 area = 10 square inches (easy memory trick: find the area of a square, gives you squared units) Volume is usually done in 3 dimensions (such as length x width x height for a box). So, you would have to multiply out your units. example: find the volume of a box that is 2 in long and 5 in wide and 3 in tall volume = length x width x height volume = 2 in. x 5 in. x 3 in. volume = 2*5*3 in.*in.*in. volume = 30 in.^3 volume = 30 cubic in. (easy memory trick: find the volume of a cube, gives you cubed (cubic) units) as for your followup question, since you are only multiplying or dividing by a number, and not a number with units attached to it, the units do not change (still square units f....

Question : we all know that for calculating area or perimeter of a circle, we should use pie. how the value of pie is determined and what is its importance
Answer : Its just a ratio between a perfect circle's diameter and its circumference which is also a ratio for its radius squared and its area. You can read all about it at wikipedia but I bet you will lose interest halfway through if not sooner. Determined by somebody in pretty much all ancient cultures, useful for architechture mostly. Just think if it didn't exist how you would figure it out? You dont want to have to always physically measure a circle with string or something...so you take a bunch of previous measurements and say...heh, the diameter and the circumference seem to have a constant ratio...le voila! Do you have a math paper to write or something and you dont know how you use a search engine or wikipedia? http://en.wikipedia.org/wiki/Pi.. More from Yahoo Answers
