I guess you could say radius (r) and the symbol pi, and the number 2:
- Circumference = 2 * pi * r
- Area = pi * r^2

The circumference od a circle is less then three time the length of the diameter?
No. The formula for circumference of a circle is pi x diameter. As pi is 3.14... then the circumference will be at least 3.14 times the diameter.
What do you do when you have a formula of 2 pi r?
That's the formula for the circumference of a circle, when you know the radius. What you do is multiply all three together. Pi is approximately 3.14, and r stands for the radius. The result of the multiplication is the circumference.
What is the circumference of a circle whose diameter is 3 ft?
A circle with a diameter of three feet has a circumference of 9.4 feet.
What is the circumference of a circle 124ft in diameter?
Circumference of circle: 124*pi = 389.557 feet to three decimal places
What is the circumference of a 1.675 inch diameter circle?
Circumference of the circle: pi*1.675 = 5.262 inches to three decimal places
The circumference od a circle is less then three time the length of the diameter?
No. The formula for circumference of a circle is pi x diameter. As pi is 3.14... then the circumference will be at least 3.14 times the diameter.
What do you do when you have a formula of 2 pi r?
That's the formula for the circumference of a circle, when you know the radius. What you do is multiply all three together. Pi is approximately 3.14, and r stands for the radius. The result of the multiplication is the circumference.
What is the area of a circle with a circumference of thirty three units?
Remember that the formula for the circumference of a circle is 2πr, with r being the radius. So 2πr is 33. we can divide this number by pi to get the diameter. According to a calculator, 33 / π = 10.50423. Now the formula for the area of a circle is πr2. So we need to divide 10.50423 by 2. The result is 5.25211. This is r. π(5.25211)2 = 86.65987. So the area of a circle with a circumference of thirty three units is 86.65987 units.
What is the circumference of a circle 1 inch times three?
circumference of a circle = diameter*pi or 2*pi*radius
What is the circumference of a circle 124ft in diameter?
Circumference of circle: 124*pi = 389.557 feet to three decimal places
What is the circumference of a circle whose diameter is 3 ft?
A circle with a diameter of three feet has a circumference of 9.4 feet.
What is the circumference of a 1.675 inch diameter circle?
Circumference of the circle: pi*1.675 = 5.262 inches to three decimal places
What is the circumference of a circle whose radius is 6?
Circumference of circle: 2*pi*6 = 37.699 units to three decimal places
What is the circumference of a circle with a radius of 6 cm?
Circumference of the circle: 2*pi*6 = 37.699 cm to three decimal places
How do you divide a circle with 9cm diameter in three equal parts?
Construct a circle with a 4.5 radius. The circle's circumference is 360 degrees. So mark out 3 by 120 degrees on the circumference and join them to the centre of the circle which will divide the circle into three equal parts.
How does the circumference of a circle change if you triple its diameter?
three times
What are the three basic parts of a circle?
Its circumference Its diameter Its radius
