How do you find the of a circumference of circle in math?
the formula is: circumference= p*diameter
A piece of string 25cm long goes exactly once around the edge of a plate in the form of a quadrant Calculate the area of the quadrant?
Presumably the plate is completely flat. The circumference will be 4*25 = 100 cm. First find the radius of the plate by rearranging the formula: 2*pi*radius = 100cm radius = 100/2*pi = 15.91549431 cm. Now use the formula pi*radius2 to find the area of the plate, and then divide your answer by 4 to give you the area of the quadrant. pi*15.915494312 = 795.7747155/4 = 198.9436789cm2. Therefore, the area of the quadrant is 199 cm2 correct to three significant figures.
How do you find the circumference of a circle with the radius of 84?
The circumference is approximately 527.79 units. The formula is: C = 2*Pi*r
You have the circumference and you need to know the diameter?
The formula for finding circumference is 2∏r (or ∏d). So to find the diameter, you would divide the circumference by pi (3.14, approximately).
What is the diameter of a circle whose circumference is 47.1cm?
Well, isn't that a happy little question! To find the diameter of a circle when you know the circumference, you can use the formula: diameter = circumference / π. So, for a circumference of 47.1cm, the diameter would be 47.1 / π ≈ 15cm. Just imagine that circle coming to life on your canvas, bringing joy and balance to your painting.
What is the formula to find circumference when you are given the radius?
To find the circumference of a circle the formula is: 2*pi*radius or diameter*pi
How do you find the of a circumference of circle in math?
the formula is: circumference= p*diameter
How do you find the circumference with the pie formula?
circumference = pi multiplied by the diameter
How do you answer the formula of a circumference?
to find the circumference of a circle you do 2 times3.14timesthe radius
How do find the circumference of a circle?
The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.
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).
What is the formula to find the distance around a quadrant?
It is the sum of its 4 sides which is its perimeter.
If the area of a circle is 201.06 then the circumference of the circle is?
The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle. To find the circumference, you first need to find the radius by using the formula for the area of a circle (A = πr^2). Given that the area is 201.06, you can solve for the radius. Once you have the radius, you can plug it into the formula C = 2πr to find the circumference.
What is the formula to find the circumference of a circle with the diameter given?
Circumference = (diameter) multiplied by (pi)
What formula is used to find the circumference when you know the radius?
Circumference=2*pi*radius
How do you determine the circumference of a circle if you know the radius?
use the formula pi*diameter = circumference and the formula diameter = 2*radius and combine them 2pi*radius = circumference now you have a formula that you can just plug you numbers into. if you have 3 as your radius, then this is how to find the circumference 2pi*3=circumference 6.28*3=circumference 18.84=circumference
Who discovered the formula of how to find out the circumference of a circle?
Archimedes
