Conceptually, the radius is the distance from the center of the circle to any point on its edge.
If you know the circumference of the circle, then the radius is the circumference divided by 2 times pi.

What happens to the circumference of a circle when the radius is doubled?
The circumfrence would double Example : C of 5 cm radius circle = 3.14 *2*5 C=3.14 C of 10cm radius circle = 3.14*2*10 C =62.8
What is the circumference of a circle with a radius of 20 feet?
Circumference of a circle equals Pi times the double the radius C = 2 x 3.14 x radius C= 2 x 3.14 x 20 C = 125.6 The circumference of a circle with a 20 foot radius is 125.6 feet.
How do you express the area of a circle as a function of its radius?
If a circle has radius r, then the area of the circle is pi r2, pi being about 3.14159. I beleive the function you are looking for is A(c)=c/2*r
If a circle has a radius of 9m what is the diameter?
C = 56.549m
What is the circumference of a circle of radius 3.8?
C = 23.876
What is the radius of a circle if given the circumfrence?
The circumference (c) of a circle = 2πr (where r = radius). Therefore if you know the circumference, the radius (r) = c/2π.
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
What happens to the circumference of a circle when the radius is doubled?
The circumfrence would double Example : C of 5 cm radius circle = 3.14 *2*5 C=3.14 C of 10cm radius circle = 3.14*2*10 C =62.8
What is the relationship between the chord and the radius of circle?
The relationship between the chord and the radius of the circle is Length of the chord = 2r sin(c/2) where r = radius of the circle and c = angle subtended at the center by the chord
If circle A has a radius of 3 cm and circle B has a radius of 4 cm and circle C has the same total area as circles A and B combined hoe do you determine the radius of circle C?
The formual for area is: A = πr2 so the area of circle A (assuming π=3.142) is 28.278cm2, and the area of circle B is 50.272cm2.Their combined area of 78.55cm2 is the area of circle C.The formula for radius is: square root of A/π78.55 ÷ 3.142 = 25, the square root of 25 is 5The radius of circle C is 5cmArea of Circle A = π32 = 9πArea of Circle B = π42 = 16πArea of Circle C = 9π + 16π = 25πLet r = radius of Circle C thenπr2 = 25π : r2 = 25 : r = 5.
C program on how to calculate circumference of a circle?
int radius = 2; int output; radius = radius * 2; output = radius * Math.PI; Console.WriteLine(output);
What is the circumference of a circle with a radius of 20 feet?
Circumference of a circle equals Pi times the double the radius C = 2 x 3.14 x radius C= 2 x 3.14 x 20 C = 125.6 The circumference of a circle with a 20 foot radius is 125.6 feet.
Work out the radius of a circle from the circumference?
c=2*pie*r c= circumference r= radius.
How to solve radius of a circle when it's in decimals?
r = d * 0.5, r = C / (2 * 3.14), r = √(A / 3.14) The radius of a circle when the diameter is known: d = 2 * r d is the diameter of the circle r is the radius of the circle r = d / 2 = d * 0.5 The radius of a circle when the circumference is known: C=2πr C is the circumference of the circle π is a constant approximately equal to 3.14 r = C / (2 * π) = C / (2 * 3.14) The radius of a circle when the area is known: A=π(r)^2 A is the area of the circle r = √(A / π) = √(A / 3.14)
How do you express the area of a circle as a function of its radius?
If a circle has radius r, then the area of the circle is pi r2, pi being about 3.14159. I beleive the function you are looking for is A(c)=c/2*r
