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.
How do you find the radius of a circle with a circumference of 73.5?
use the circumference formula of a circle circumference of a circle=2*pi*r pi=22/7 r-radius of a cirle Now the answer for the problem is 11.69
What is the circumference of a circle is 22 units what is the area?
Divide the circumference by (2 x pi) to get the radius. Then use the formula for the area of the circle.
What is the circumference of a circle that has a diameter of 5 inches Use 227 for pi?
by the way 22/7
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 calculate circumference of a circle?
You use a protractor.
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.
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.
How do you know circumference?
The circumference is the perimeter of a circle, total outer length of a circle. Use 2 x (pi) x r to calculate the circumference, where (pi)= 3.142, r= radius of circle. :)
What is circumference of a circle with 154 square inches?
Use the standard formula for the area of a circle to find out the circle's radius. Then multiply that by 2 x pi, to get the circumference.
