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?
To find the diameter of a circle with a given circumference, you can use the formula: circumference = π * diameter. Given a circumference of 47.1 cm, you can rearrange the formula to solve for the diameter. Divide the circumference by π (approximately 3.14159) to find the diameter. Therefore, the diameter of a circle with a circumference of 47.1 cm is approximately 15 cm.
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 answer the formula of a circumference?
to find the circumference of a circle you do 2 times3.14timesthe radius
How do you find the circumference with the pie formula?
circumference = pi multiplied by the diameter
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 formula is used to find the circumference when you know the radius?
Circumference=2*pi*radius
What is the formula to find the circumference of a circle with the diameter given?
Circumference = (diameter) multiplied by (pi)
Who discovered the formula of how to find out the circumference of a circle?
Archimedes
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
