Best Answer

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.

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 :-)

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.

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.

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

Multiply the small number by another small number and keep doing this until you get the big number but a quicker way would to just use a calculator.

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)

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.

Circumference is diameter times Pi, you do the math.

-- 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.

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.

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.

The Men's Size 7 regulation basketball has a circumference between 29.5-30 inches. It weighs 20-22 ounces, and has a diameter of 9.39 inches.The Women's Size 6 regulation basketball has a circumference between 28.5 and 28 7/8 inches. It weighs 17.5-19.5 ounces and has a diameter of 9.07 inches.The Junior's Size 5 basketball has a circumference between 27.25 to 27.75 inches. It weighs 16.6-18 ounces and has a diameter of 8.7 inches. It is recommended for boys and girls under 12 years old (junior league).The mini Size 3 basketball has a circumference between 22 to 22.5 inches. It weighs 10-11 ounces and has a diameter of 7 inches. It is recommended for small children (age 5-8)

That depends on the definition of "small penis". Average size of the adult penis is 5.1-5.9 inches long with a circumference of 4.85 inches(thats circumference, not diameter). The average size at the beginning of puberty is about 2.4 inches long with adult size reached about 5 years later.
