If you would like to know the circumference of a 15" diameter circle this is the formula:

circumference = radius x 2 x pi

circumference = diameter x pi

in our case:

circumference = 15" x 3,14

circumference = 47 ,1" (that's 119,634 cm)

circumference = radius x 2 x pi

circumference = diameter x pi

in our case:

circumference = 15" x 3,14

circumference = 47 ,1" (that's 119,634 cm)

What do you mean? The circumference of a circle having a radius or 15"? If so, it will be* [2 x 3.14 x 15] = 94.2"*.

Since circumference of a circle = 2 x (pai) x r (r = radius)

The circumference of a circle is two times pi times the radius, where pi is about 3.14159. With a radius of 8.7mm, the circumference is about 54.7mm.

The circumference of a circle is given by the expression

Circumference= 2* PI* Radius of circle

**C=2*Pi*R**

The area is given by

**Area of a disk with radius R** **= Pi* R*R** or **PI*R^2**

**Area= PI*R^2**

Circumference= 2* PI* Radius of circle

The area is given by

The formula for circumference of a circle is c=2*pi*r, using 3.14 for pi and 3.2 inches for the radius.

c=2 * 3.14 * 3.2

Good luck.

Paul

c=2 * 3.14 * 3.2

Good luck.

If you know the center, measure the distance between the center and one point on the circumference. Measure with the opening of a compass and report on a ruler, or use a ruler.

Take the measure of the radius and multiply by 2. Any other indirect way of getting the radius does not constitute a measure but a calculation.

The diameter of a circle enters in two formulas.

Length of Circumference: C=Pi*D (D diameter) ====>**D=C/Pi**

Area of the disk A=Pi *D^2/4 =====>**D=SQRT(4*A/Pi)**, SQRT is the square root operation.

Take the measure of the radius and multiply by 2. Any other indirect way of getting the radius does not constitute a measure but a calculation.

To get a circle with a perimeter of 18 inches, you want a diameter of about 5.73 inches (just under 5 3/4 inches) or a radius of 2.86 inches (call it 2 7/8 inches). Get a compass, set its legs 2 and 7/8 inches apart, put one end at the center, and turn.

The radius and the coordinates of the center will completely define a circle. Some other measurements include the diameter, circumference, and area. Then there are parts of the circle, such as arc and chord.

30" diameter? Radius is 15" (half of diameter).

30" circumference (distance around) is a little more complicated...

The number is the ratio of the circumference of a circle to the diameter. The value of is approximately 3.14159265358979323846...The diameter of a circle is twice the radius. Given the diameter or radius of a circle, we can find the circumference. We can also find the diameter (and radius) of a circle given the circumference. The formulas for diameter and circumference of a circle are listed below. We round to 3.14 in order to simplify our calculations.

Hello my friend, I am Jonas I work as a programmer in some various programming languages. Here try this code:

This program is design to output the Diameter, circumference, and area given a radius of a circle. #include <iostream.h> int main() { int radius, diameter, circumference, area, pi; cout << " Enter the radius of a circle\n"; cin >> radius; pi = 3.14159; diameter = 2 * radius; circumference = 2 * pi * radius; area = pi * (radius)^2; cout << "Diameter formula executing.....(2 x r)\n"; cout << "Diameter is " << diameter << endl; cout << "circumference formula executing.....(2 x pi x r)\n"; cout << "circumference is " << circumference << endl; cout << "area formula executing......(pi x [r x r])\n"; cout << "area is " << area << endl; return 0; }

Also if you need tutorial you can visit this site Learning C++ .Hope this solution will able to help your problem solved. If you need more assistance just reply to this post or send me a mail at geo_jonas@yahoo.comThank you and Godbless.
