Asked by Hey,I'm just asking

i need some help understanding the formulas for finding the are for a circle and finding the Circumference.
and the formula they give me i still don't understand can you guys help me understand the easier way to look at the formula?
Answered by oobleck
can't think of a way.
Do you have trouble with the area of a rectangle or a triangle?
Those are just as complicated.

There are geometric justifications for the circular formulas, but if you can't handle the simple formulas, I don't think you'd be happy with the concepts involving their derivation.

Maybe you could try google -- <u>why is the circumference 2 pi r?</u> or something.

Im kinda understanding it so to find the circumference we multiply the diameter by 2?
Answered by Ms. Sue
No.

C = pi * 2 * r
Answered by oobleck
or, just C=πd, where d is the diameter

I'm learning this currently. Circuference=2 times 3.14 times the radius. The raidius is 2 times less than the diameter. Radius=diameter divided by 2.
Area=3.14 times the radius squared. So it would look like this for area: A=3.14(radius times radius). There you go!
