If the area of a circle and its circumference have the same numerical value what is the length of the radius?
Area = pi*r2 = 2*pi*r = circumference then r2 = 2r so that r = 2
What is the radius of a circle of a circumference of 121?
To find the radius of a circle with a circumference of 121, you can use the formula for the circumference of a circle: C = 2πr, where C is the circumference and r is the radius. Given that the circumference is 121, you can plug this value into the formula and solve for the radius. Dividing 121 by 2π will give you the radius of the circle, which is approximately 19.24 units.

What is the definition of cercumference and radius of pi.?
Circumference is the enclosing boundary of a curved geometric figure, especially a circle. Radius is a straight line from the center to the circumference of a circle or sphere. Pi is the numerical value of the ratio of the circumference of a circle to its diameter and does not have a circumference or radius of its own.

How can the distance around a circle be the same as the area inside a circle?
It cannot be because the first is a measure of length whereas the second is a measure of area. Basic rules of dimensional analyses states that such comparisons are meaningless.However, the numerical value of the circumference of a circle and the numerical value of its area will be the same if the radius has a value of 2 in some measurement units.A circle with radius of 10 cm has a circumference of 63 cm and an area of 314 cm^2 and these are clearly not equal. But if the measurements are taken in units of 5 cm, then the radius is 2 units and the circumference is 12.6 units while the area is 12.6 square units - the same numeric value.
The circumference of a circle is 132cm what is the radius of the circle in centimeters?
To find the radius of a circle when given the circumference, you can use the formula for the circumference of a circle: C = 2πr, where C is the circumference and r is the radius. Given that the circumference is 132 cm, you can plug this value into the formula: 132 = 2πr. To solve for the radius, divide both sides by 2π: r = 132 / (2π) ≈ 21 cm. Therefore, the radius of the circle is approximately 21 centimeters.
What is the circumference of a circle with a radius of 8?
Oh, dude, you're hitting me with some math here! So, the circumference of a circle is calculated by multiplying the radius by 2π. With a radius of 8, that means the circumference would be 16π. But, like, if you want a numerical answer, it's around 50.27 units.
How do you calculate the radius from the circumference?
Of a circle: divide the length of the circumference by the value of Pi (about 3.14159). The answer is the diameter. Half of the diameter is the radius
What is the formula for circumference of a circl?
The circumference of a circle is the length around it. The circumference of a circle can be calculated from its diameter using the formula: Circumference of a circle = 2*pi*radius orCircumference of a circle = pi*diameterwhere r is the radius and d is the diameter of the circle, and � (the Greek letter pi) is defined as the ratio of the circumference of the circle to its diameter.(the numerical value of pi is 3.141 592 654 589 793...).d * pior 2 * r * piWhere d is diameter and r is radius and pi = 3.14159
How do you find the radius of a circle when the circumference is given?
Divide the circumference by the value of Pi, then halve that result.
If the circumference of the circle is 75.36 what is the radius?
To find the radius of a circle when given the circumference, you can use the formula: circumference = 2 * π * radius. Given that the circumference is 75.36, you can plug this value into the formula and solve for the radius. First, divide the circumference by 2π to find the radius. The radius of the circle would be 75.36 / (2 * 3.14159) ≈ 12. The radius of the circle is approximately 12 units.
The development of Circumference?
pi = Cirumference C divided by diameter d. The circumference is the distance around a closed curve. Circumference is a kind of perimeter. Circumference of a circle The circumference of a circle can be calculated from its diameter using the formula: C = pi times d Or, substituting the diameter for the radius: C = pi times 2 r where r is the radius and d is the diameter of the circle, and pi is defined as the ratio of the circumference of the circle to its diameter. The numerical value of pi is 3.141 592 653 589 793...
