Pi is not a variable. Pi is an irrational real positive number. The value of pi is approximately 3.14159
irrational means there is no way to write the exact value of pi. It can not be written with a finite number of decimal points. It can not be written as a fraction. it can not be written as the nth root of any number.
real means it is not generated by taking the square root of a negative number and it is not generated by dividing anything by 0 .
positive means it is greater then 0.

What is the circumference of a basket with a diameter of 20.5 inches?
20.5 pi ie 64.4 in
Circumference of 1.5 cm diameter circle?
1.5 pi ie 4.71 cm
Give five example of constant and variable?
pi, e, phi, 1,2,3,4, etc.
The diameter of a can of corn is 77 mm. What is the circumference?
77 x pi, ie close to 242mm
What is the circumferance of a circle if the diameter is 19?
19 pi, ie 19 x 3.1415 = 59.69
Assign the value of pie ie 3.142 to a variable with requisite data type?
float pi = 3.142; // Note: pi is an irrational number, there is no "exact" value of pi
If the perimeter is 20 what is the highest area you can get?
A circle, radius 10/pi has an area of pi x 10/pi x 10/pi ie 100pi/pi2 ie 100/pi ie 31.8; A square 5 to the side has an area of 25.
Is the symbol pi considered a variable in math?
No. It is a constant. A variable is something that changes value in certain circumstances; pi always has the same value.
A constant that multiplies a variable?
A constant that multiplies a variable is no longer a constant. By its very definition, a constant is something that can never be different. The result of variable multiplication is thus a variable, not a constant.I would say that the above answer is not necessarily true. The common equation for the area of a circle is: area = pi * r2The fact that you are multiplying the mathematical constant pi by a variable does not change the value of pi.Agree with the second answer. Jsut to add, a constant that multplies a variable is called a coefficient.
What are numeric constants in basic?
It is a variable that can not be changed such as PI.
Is pi a coefficient?
Yes--in that it is a constant that typically precedes a variable.
What are numeric constant in visual basic?
It is a variable that can not be changed such as PI.
If a circle has a radius of 12 incheswhat is the diameter?
2 x pi x 12 in, ie 24 pi inches
What is the diameter if the circumference is 42 ft?
42/pi ie 13 feet 4½ inches, assuming pi to be 3.14
What is the area of a circle with a radius equals 22 ft?
22 x 22 x pi, ie 484 pi sqft.
What is the circumference of a basket with a diameter of 20.5 inches?
20.5 pi ie 64.4 in
What is the circumference of a circle if the diameter is 10 inches?
31.4 inches, ie 10 pi
