Why do we use pi?
We use it to calculate the circumference of a circle.
How does an architect use pi?
To calculate the area/circumference of a circle when designing something circular with a limited amount of material. i.e. you have to design a bronze circle and only have 27 sq ft of bronze. You have to calculate the circumference to see if you need to make the circle smaller or not.
Define what the circumference of a circle?
The circumference of a circle is the perimeter of the circle for a given diamater.
What may be calculated from its diameter?
If by "it" you mean a circle, once you know the diameter, you can calculate its radius, its circumference, and its area.
What is circumference of a 9 circle?
The circumference of a 9 circle is: 28.3
How do find the circumference of a circle?
The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.
If a circle has a diameter of 8 cm then what is the circumference of the circle?
A simple formula to calculate the circumference of a circle: so in this case:
C program on how to calculate circumference of a circle?
int radius = 2; int output; radius = radius * 2; output = radius * Math.PI; Console.WriteLine(output);
What is a rule to describe how to estimate the circumference of a circle when you know its diameter?
The circumference, C, of a circle is given by the formula
Pi can be used to calculate the blank of a circle?
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
How do you calculate circumference of a circle?
You use a protractor.
Why you are using pi to calculate circumference of the circle?
Because the ratio of the circumference to the diameter of every circle is pi. So circumference = pi*diameter.
How do you calculate the circumference of a circle given the diameter or the radius?
Circumference = diameter*pi
How do you calculate the diameter and the circumference of a circle?
Doubling the radius will give the diameter and times this by pi will give the circumference of the circle.
Why do we use pi?
We use it to calculate the circumference of a circle.
IF the circumference of a circle is 6.28 what is the area?
The circumference and area of a circle, with radius r is: circumference = 2*pi*r and area = pi*r2 Use the first to calculate r and then the second to calculate the area.
What is the ciruumference of a circle?
The circumference is essentially the perimeter of the circle, or the distance around the circle. To calculate the circumference of a circle, use the formula C = 2 * pi * r. Circumference = two times pi times the radius of the circle.
