Why would you use a formula to determine the circumference of a circle rather than measuring the circumference?

Because the circumference of a circle isn't a straight line its hard to measure, even if you have a flexi-ruler, your never going to be able to line it up to get an exact measurement. Therefore its much easier to measure the diameter and use the formula

How the use of constants rather than literals can simplify software maintenance.?
Say you put into your program the formula to calculate the area of a circle given its radius R asA = 3.141592 * R * RComputer science teachers will usually mark you down for this, saying you should instead write it asPI = 3.141592...A = PI * R * RBecause that way, should the value of pi ever change, you can just change it in the header and anywhere you've used the value in the program will automatically change with it.Okay, that's not super likely, but suppose instead you had formulas to calculate the area of the circle, and the volume of a sphere, and the circumference of a circle, and the surface area of a sphere, and you run your program and notice that the answers you're getting are just slightly off what they should be. You look, and eventually find that the book you used to look up the value of pi had a typo and you've been using 3.145192 instead. Now you have to find everywhere it occurs in the program and fix it. If you had defined it in the header, you make the change in one spot, and its instantly fixed everywhere in the program.

Why would you use a formula to determine the circumference of a circle?
There is a constant relationship between the radius of a circle and its circumference. This is expressed in a formula.
Who discovered the formula for the circumference of a circle?
Archimedes created the formula for measuring the circumference of a circle he used many-sided polygons, both inside and out to approximate it.
What is the circumference of a circle measuring 8feet 10inches?
It has a circumference of 333.01 feet.
What is the formula for the circumference of a circle from the area?
In order to convert the area of a circle to the circumference of the circle, divide by the radius and multiply by two. The formula for the circumference of a circle is pi times the diameter.
How do you determine the circumference of a circle if the radius is given?
Use this formula where r is the radius: C = 2Pi(r)
What is the formula for the circumference of a circle if the diameter is 8.70 m?
The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.
What is the circumference of a circle with radius measuring 28cm?
The circumference of a circle with radius measuring 28cm is about 175.9cm (C = r x 2 x Pi).
How do you determine the circumference of a circle if you know the radius?
use the formula pi*diameter = circumference and the formula diameter = 2*radius and combine them 2pi*radius = circumference now you have a formula that you can just plug you numbers into. if you have 3 as your radius, then this is how to find the circumference 2pi*3=circumference 6.28*3=circumference 18.84=circumference
Formula for finding the circumference of cone?
There is no circumference of a cone, but, we only do the circumference of the circle. the formula for the circle is pi times D. D= Diameter
Formula of circumference?
Formula of Circumference of a circle: 3.14*Diameter of the circle. You could also do: 3.14*3.14*radius.
What does circumference look like?
Of a circle? It's the perimeter of the circle. Imagine putting measuring tape around a circle, the you would get a circumference
What is the formula for the diameter or a circle?
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
