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
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 radius of a circle if given the circumfrence?
Remember the circle eq'n.;- C = 2 pi r By algebraic rearrangement r = C / (2*pi)
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 = β(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=2Οr C is the circumference of the circle Ο is a constant approximately equal to 3.14 r = C / (2 * Ο) = C / (2 * 3.14) The radius of a circle when the area is known: A=Ο(r)^2 A is the area of the circle r = β(A / Ο) = β(A / 3.14)
What is the formula for cicumfrance?
The formula for the circumference of a circle is C = 2Οr, where C is the circumference and r is the radius of the circle.
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
