To find the circumference of a circle with a diameter of 5.6 cm, we first need to find the radius which is half of the diameter.
Radius = Diameter / 2 = 5.6 cm / 2 = 2.8 cm
Now, we can find the circumference of the circle using the formula:
Circumference = 2 * π * radius
Circumference = 2 * π * 2.8
Circumference ≈ 2 * 3.14159 * 2.8 ≈ 17.6 cm
Therefore, the circumference of the circle is approximately 17.6 cm.
Next, to find the area of the circle, we use the formula:
Area = π * radius^2
Area = 3.14159 * 2.8^2 ≈ 3.14159 * 7.84 ≈ 24.618 cm^2
Therefore, the area of the circle is approximately 24.618 cm².
Radius = Diameter / 2 = 5.6 cm / 2 = 2.8 cm
Now, we can find the circumference of the circle using the formula:
Circumference = 2 * π * radius
Circumference = 2 * π * 2.8
Circumference ≈ 2 * 3.14159 * 2.8 ≈ 17.6 cm
Therefore, the circumference of the circle is approximately 17.6 cm.
Next, to find the area of the circle, we use the formula:
Area = π * radius^2
Area = 3.14159 * 2.8^2 ≈ 3.14159 * 7.84 ≈ 24.618 cm^2
Therefore, the area of the circle is approximately 24.618 cm².
