What is the circumference of a circle with a diameter equaling with 7 centimeters in length use 314 for pi?
If you mean 3.14 for pi then the circumference is: 7*3.14 = 21.98 cm
What is the circumference of a circle with an area of 314 in2?
Tells you the answer is 2*sqrt(314*pi) inches, which is approximately 62.82 inches Seriously though. Use metric units in maths it makes everything just work!
What formula do you use if you know the diameter of a circle and want to find the circumference?
circumference of a circle = pi * diameter.
How do you use the diameter to find the circumference of a circle?
Multiplying the diameter by pi (approx 3.1416) will give you the circumference of the circle.
How do you calculate circumference of a circle?
You use a protractor.

What is the radius of a circle if its circumference is about 314 feet?
You have to use the equationcircumference is equal to the radius multiplied by "pi" multiplied by twoC = 2 * π * rBecause your circumference is a known value, the only unknown value left is the radius. Simply solve the equation.314 / (2*π) = rr = 50.0 feet
What formula do you use if you know the diameter of a circle and want to find the circumference?
circumference of a circle = pi * diameter.
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
Why do we use pi?
We use it to calculate the circumference of a circle.
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.
What are the two formulae you can use to find the circumference of a circle?
Circumference of a circle = 2*pi*radius or pi*diameter
How do you use the diameter to find the circumference of a circle?
Multiplying the diameter by pi (approx 3.1416) will give you the circumference of the circle.
How do you find and use the circumference of a circle?
The circumference of a circle is the distance around the outside of the circle. It could be called the perimeter of the circle. The circumference of a circle can be found by multiplying pi ( n = 3.14 ) by the diameter of the circle. If a circle has a diameter of 4, its circumference is 3.14*4=12.56. If You know the radius, the diameter is twice as large.
How do you calculate circumference of a circle?
You use a protractor.
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.
