How do you find the circumference of a circle when you know the area?
To find the circumference of a circle when you know the area, you first need to find the radius of the circle using the formula for the area (area = πr^2). Once you have the radius, you can calculate the circumference using the formula for the circumference (circumference = 2πr).
What is the radius in centimeters of a circle that has a circumference of 16pie centimeter?
OK, The circumference of a circle is 2 times pi (3.14) times the radius. SO the radius is = to circumference (5cm) divided by 2 times pi. 5 divided by 6.28 = .796 time 2 gives us a diameter of = 1.59 centimeters. We could also use Pi = cicumference/diameter therefore 3.14=5/x Multiply both side by x and 3.14 x = 5 Divide both sides by 3.14 and you get x= 5 divided by 3.14 which equals 1.59 cm
What is the area of a circle with circumference 9.42?
The formula for the circumference of a circle is 2πr, where r is the radius. We can rearrange this formula to solve for the radius: r = circumference / (2π) = 9.42 / (2 * 3.14159) = 1.5. Then, using the formula for the area of a circle (πr^2), the area is π * 1.5^2 ≈ 7.07 square units.
If the area of a circle is 201.06 then the circumference of the circle is?
The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle. To find the circumference, you first need to find the radius by using the formula for the area of a circle (A = πr^2). Given that the area is 201.06, you can solve for the radius. Once you have the radius, you can plug it into the formula C = 2πr to find the circumference.
How do you find the area of a circle in a square?
To find the area of a circle inscribed in a square, you can use the formula for the area of a circle (πr^2) and the properties of a square (all sides equal). Since the diameter of the circle is equal to a side of the square, you can find the radius of the circle by halving the side length of the square. Then, plug the radius value into the area of a circle formula to find the area.
