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)

How to solve the circumference by using fomulae p=2

The formula is simply this: C = (pi)d. In this equation, "c" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi, which is an approximation of 3.14.

The circumference of a circle is 47.1 feet. What is the diameter of the circle?

The circumference of a circle is C=2 * pi * r or C= pi * d.

What do we know? C=47.1 and pi.

What are we trying to calculate? d

Put what we know in the equation and solve for d.

47.1 = pi * d

To isolate d, we have to divide both sides by pi.

------ = d

I get 14.99' or approximately 15' as the diameter.

Good luck,

What is the radius of a 30'' pipe

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

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

The number pi.gif is the ratio of the circumference of a circle to the diameter. The value of pi.gif 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 pi.gif to 3.14 in order to simplify our calculations. diam_formula.gif circum_formula.gif

Example of program in c++ and there code

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.
