What is the best estimate of the area of a circle with a diameter of 10 cm?
Laxgirl20
You have to calculate the radius - half the diameter. Then square the radius, and multiply by pi (approximately 3.1416). If you want to do a mental estimate, round pi to 3.

How do you find the circumference and area of a circle?
-- If you know either the area or the circumference of the circle, you can calculate the other one. -- If you don't know either the area or the circumference, then you have to either measure the circle's diameter, or ask around and try to find someone who already knows what the length of the diameter is. -- Once you have the diameter, take 1/2 of it. That's called the circle's "radius". -- The area of the circle is (pi) x (radius)2 -- The circumference of the circle is (2 pi) x (radius) or (pi) x (diameter). (Pi) is a number that can never be exactly written down, so the best you can do is use some number that's close. The closer your number is to (pi), the closer your answer will be to the truth, but it can never be exactly and perfectly correct. (Pi) is approximately 3.1415926 . But the easiest and most practical way to work with it is to use 22/7 for it. If you do that, then your answers are only about 0.04 percent wrong, and that's actually pretty darn good.
