Area = Pi multiplied by the radius squared
Circumference = Pi multiplied by the diameter
r = 10 in./2 = 5 in.
A = (3.1415)(5 in.)(5 in.)
= 78.54 in.2
C = (3.1415)(10 in.)
= 31.42 in.
Therefore, a small circle with a diameter of 10 inches has an area of about 78.54 inches squared and a circumference of about 31.42 inches.

What are facts about pi?
Pi is a transcendental number.It starts with the number 3! ---- How about that it is a never ending number....there have been contests to see who can memorize the largest amount of numbers included, and to date, the winner has been Akira Haraguchi of Japan, who claimed to have memorized 100,000 digits. However, Guiness Book of Records has not verified his ability, so the recognized winner is Lu Chao of China, at some 67,890 numbers of pi. Another cool fact about pi is that it is always equal to the ratio of the circumference of a circle/its diameter. pi=c/d. Always true, regardless of how large or small the circle is. Have fun :-)
What is the square foot of a 21 foot round pool?
If 21 feet is the diameter, divide it by 2 to get the radius. Then use the formula for a circle: area = pi x radius2. 350 sq ft NOT the 35 the other people answered. A sheet of plywood 4' by 8' is 32 Sq ft thats a really small pool.
Is a circle a 360 sided figure?
No, because if a circle has a set amount of sides, then it must have a certain amount of angles, reguiring the vertex of the angle to be farther from the center than say,the midpoint of its adjacent angle. This violates a criterion of a circle, because not all (no matter how small the difference is) radii are equidistant from the center.
Should you measure a pool in centimeters or in meters?
meters-centimeters are really small, about a third of an inch. Meters are about a yard. Would you measure a pool in thirds of inches or yards? Exactly
What is the Greek small letter for Alpha?
The Greek small letter for Alpha is α.
The diameter is 12 and the circumference is 37.68 for the large circle for the small circle the diameter is 6 wat is the circumference?
For the small circle of diameter 6, the circumference is 18.84.
The diameter is 12 and the circumference is 37.68 for the large circle for the small circle the diameter is 6 what is the circumference?
The circumference of the small circle would be 18.84.
The diameter of the small wheel was 7 inches. The circumference was about 22 inches. Write the ratio of the circumference to the diameter of the circle as a decimal number rounded to the nearest hundredth?

How much longer is the circumference of a 12 inches diameter pizza have than an 8 inches diameter pizza?
Circumference of a circle = pi DCircumference of the big one = 12 piCircumference of the small one = 8 piDifference = (12 pi - 8 pi) = (12 - 8) pi = 4 pi = 12.5664 inches (rounded)
Will a circle with a radius of 4 inches fit inside a circle with a diameter of 5 inches?
no because the radius is half the diameter so it must be multiplied by two in order to find the diameter of that circle which is 4 times 4 equals to 8 so the circle which has a diameter of 5 inches is much to small for a circle with a radius of 4 inches to fit.
The diameter of the front wheel of a small bike is 20 inches In one full turn of the wheel the bike travels about?
Circumference is diameter times Pi, you do the math.
How do you find a circumference?
Circumference of a circle is pi * diameter. Diameter is 2 * radius. So if you know the radius, circumference is 2 * pi * radius. Now choose an appropriate approximation for pi (3.14, or 3.1416, or even the fraction 22/7), depending on your application. This will work for ANY circle, no matter how big or small it is, as long as it's a true circle and not a different elliptical shape, e.g. an oval.
How do you draw a diagram that shows what pi means?
-- Draw a circle. -- Put a mark at the center, and draw a line across the whole circle through the center. -- Measure the length of the curved line all around the circle. (called the "circumference" of the circle) -- Measure the length of the straight line across the circle. (called the "diameter" of the circle) If you divide the circumference by the diameter, the result is 'pi'. It doesn't matter how big or how small the circle is. The result is always the same.
What is the average circumference of an orange?
About 3 inches. Darling, that would be the diameter (across), not the circumference (around). A small (3" diameter) orange would be 9 1/2" around, a large (4" diameter) grapefruit would be nearly 12 1/2" around. For another reference, a 12" diameter softball is about 3.8" in diameter.
