What is the radius If the circumference is 44?

r = 7cm is the answer.

Is the circumference of a circle its radius?

The circumference in terms of the radius is equal to two times the radius times 𝜋. The radius is then equal to 𝑟. With this ratio, we notice that we have an 𝑟 on either side. In its simplest form, the ratio of the circumference of a circle to its radius is two 𝜋 to one.

How do you find the circumference of a circle in a square?

Circles Inscribed in Squares

1. For a square with side length s , the following formulas are used.
2. Perimeter = 4s.
3. Area = s2.
4. Diagonal = s√2.
5. For a circle with radius r , the following formulas are used.
6. Circumference = 2πr.
7. Area = πr2.
8. So, the side length of the square is 6 cm.

How do you find the radii?

How to Find the Radius of a Circle?

1. When the diameter is known, the formula is Radius = Diameter/ 2.
2. When the circumference is known, the formula is Radius = Circumference/2π.
3. When the area is known, the formula for the radius is Radius = ⎷(Area of the circle/π).

Is circumference squared?

Correct answer: Circumference is 1 dimensional, so it makes sense that the variable is not squared as cubed. If you rather, you can use the following formula, but realize by defining diameter, it equals the prior one.

What is the radius of circle whose circumference is 132?

Circumference of circle = 132 cm. Hence, the radius of circle is 21 cm.

What is the ratio of the circumference if the circle to its radius?

2π:1
Ratio of circumference of a circle to its radius is always 2π:1.

Is the circumference of a circle squared?

Understanding the Area and Circumference of a Circle. Factoid: The area of a circle is pi (approximately 3.14) times the radius of the circle squared. The circumference is pi times the diameter.
