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
Formula for finding radius of a circle?
c=TT R Given the area, the radius = square root (area / Pi). Given the circumference, the radius = circumf/ 2Pi.
What is the radius of a circle with a circumference of 18.84?
The circumference of a circle is given by the formula C = 2πr so r = C/2π When C = 18.84 then r = 18.84/2π = 3
Given the circumference of a circle what is the radius?
Circumference equals the diameter times pi. The diameter is 2 times radius. Radius equals Circumference divided by pi then divided by 2.
What is the formula for finding the diameter of a circle when the circumference is given?
C = pi d By algebraic rearrangement d = C / pi
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
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 get the radius of a circle from the circumfrance?
To find the radius of a circle when given the circumference, you should start with the formula for circumference, which is this: circumference = 2*pi*radius To solve for the radius, you would the have to divide the circumference by 2*pi leaving you with a formula like this: radius = circumference/(2*pi) pi≈3.14159
What is the formula to find the circumference of a circle with the raduis given?
Circumference of a circle: 2 x pi x radius.
Radious formula for a cicrle?
It is not clear whether you want the formula of some aspect (area or circumference) of a circle when given its radius or a formula for its radius when given some characteristic measure of the circle.
How do you determine the circumference of a circle if the radius is given?
Use this formula where r is the radius: C = 2Pi(r)
If the circumference of a circle is 2053 feet what is the radius of the circle?
Given the circumference of a circle the radius is: r = C / 2xPI So the radius of your circle is 326.7451 ft
Formula for finding radius of a circle?
c=TT R Given the area, the radius = square root (area / Pi). Given the circumference, the radius = circumf/ 2Pi.
Given a circle with a radius of 4 which is the circumference?
The circumference is 25.1
What is the formula for finding the diameter of a circle when the circumference is given?
C = pi d By algebraic rearrangement d = C / pi
What is the formula to find a circumference if the radius is 3 and the diameter is 6?
The circumference of a circle is given by the formula C = 2πr where r is the radius. But, as the diameter is 2 x radius then the formula can be written C = πd where d is the diameter. In this example the circumference = 2π3 = 6π = 18.85 units.
How do you find the perimeter of a circle with radius 5cm?
Do note that the perimeter/circumference of a circle can be found using this formula: πD or 2πr. Hence, with the information given that the circle has a radius of 5cm, the circumference of the circle is: Formula = πD Diameter = Radius x 2 = 5cm x 2 = 10cm π = 3.14 (depending on what the question states π to be) Circumference of the circle = 3.14 x 10cm = 314cm
