How do you find the diameter of a circle knowing only the circumference?
to find the diameter of a circle when you only have the circomference you: divide the circomference by pi (approx. 3.14)
What formula is used to find the diameter when you know the circumference?
Pi X D = Circumference. To find Diamater if you know Circumference, divide Circumference by Pi (3.14).
How do you find cicumference with only knowing the radius?
To find the circumference of a circle you multiply pi, usually rounded to 3.12, by the radius. The formula for the circumference of a circle is 2*pi*radius. So double your radius, then multiply by pi, which is approximately 3.14159265 So if I had a circle of radius 2, my circumference would be 2*3.14*2 = 12.56 Good Luck!
How do you find circumference if you know diameter?
If you know the diameter and need the circumference you times the diameter of the circle by 3.14 also known as pie. That is how you get the circumference by only knowing the diameter. :)
How do you find the diameter of a circle if you know the circumference?
Divide the known circumference by pi to find the diameter of the circle.
How to find the diamater of a circle?
You double the radius.. if the radius is 10 the diameter is 20.
How do you solve the circumference of a circle?
to find the circumference of a circle, which is the distance in the outside of the circle you need to use the following formula: C=dx 3.14 or circumference equals diameter times pi. The diamater is the length of the circle from end to end. Not very difficult.
What is another way to find the area of a circle given the circumference?
Divide by pi to get the diameter. Divide the diamater by 2 to get the radius. Pi times radius squared.
If you have the diamater 4.2cm how would you find out the circumference?
Circumference of a circle = 2*pi*radius or pi*diameter Circumference = pi*4.2 = 13.19468915 or 13.2 cm to one decimal place
How do you find the diameter of a circle knowing only the circumference?
to find the diameter of a circle when you only have the circomference you: divide the circomference by pi (approx. 3.14)
How do you find the area of a semi circle knowing the radius?
count the number of sides?
How do you find the area of a circle without knowing the radius?
If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.
Why it is so important to know the area of a circle?
Knowing the area of a circle which is pi times radius squared will help you to find other properties of the circle
How do you find the circumference of a circle without knowing the radius and area?
You will have to measure some part of the circle. As long as you have absolutely no information about a circle, you can't do any calculations.
How do you find diameter knowing the circumference?
Divide the circumference by 3.14159265 (3.14 for rough approximation) to find the diameter of a circle.
How do you find out the the diameter of a circle if knowing the circumference?
Divide the circumference by the value of Pi - that will give you the diameter.
How do you find the circumference of a circle without knowing the area?
To find the circumference of a circle, you need only know the radius or diameter of the circle. The circumference of a circle is calculated as 2 x Pi x radius OR Pi x diameter. Pi is approximately 3.1415926.
