how do you find the diameter of a circle if you don't have the radius? the circumference is 628 cm.
Divide the circumference by pi, which is 3.14 (approximately). That will give you the diameter.
Circumference = pi * D
To find the diameter of a circle when you only have the circumference, you can use the formula Circumference = π * Diameter.
In this specific case, you have a circumference of 628 cm. To find the diameter, divide the circumference by pi (π), which is approximately 3.14.
Let's plug the values into the formula:
628 cm = 3.14 * Diameter
To isolate the diameter, divide both sides of the equation by 3.14:
Diameter = 628 cm / 3.14
Simplifying the calculation:
Diameter ≈ 200 cm
Therefore, the approximate diameter of the circle is 200 cm.
