Diameter, and radius (please excuse the spelling errors, im only in 6th grade). First, You have a diameter of a circle, for example your diameter is 10 than what is the radius? the radius is half of the diameter so that means that it would be 5.

Now for Circumference, The circumference of a circle is 3.14(pi)D (if the number(s)and the letter are close together that means they are suppose to be multiplied. So if you have a diameter of 8 that means your circumference is 25.12

I can help you solve problems involving fractions, decimals, ratios, and algebra. I can teach you how to do math faster, and even in your head. I can teach math definitions, and help you study, if necessary. Please do not ask any graphing, trigonometry, or calculus questions. Try to work through homework questions before asking for assistance.


I routinely process numbers of all kinds in my head, without need of a calculator.

I was an A math student while in high school.
