The area of a circle can be calculated using the formula: A = πr^2
where A is the area of the circle, π (pi) is approximately 3.14, and r is the radius of the circle.
Substituting r = 8 inches into the formula:
A = 3.14 * (8)^2
A = 3.14 * 64
A = 200.96
Therefore, the area of a circle with a radius of 8 inches is approximately 200.96 square inches.

The formula for the circumference of a circle is: C = πd
where C is the circumference, π (pi) is approximately 3.14, and d is the diameter of the circle.
Given that the circumference is 56.52 inches:
56.52 = 3.14 * d
Solving for d:
d = 56.52 / 3.14
d ≈ 18
Therefore, the diameter of the circular flag is approximately 18 inches.

The circumference of a circle can be calculated using the formula: C = 2πr
where C is the circumference of the circle, π (pi) is approximately 3.14, and r is the radius of the circle.
Given that the radius is 17 cm:
C = 2 * 3.14 * 17
C = 6.28 * 17
C = 106.76
Rounding to the nearest hundredth, the circumference of a circle with a radius of 17 cm is approximately 106.76 cm.

If the circumference of a circle is given as C = 12π, we can use the formula for the circumference of a circle: C = 2πr.
Given C = 12π, we have:
12π = 2πr
Solving for the radius:
r = 6
Now that we have the radius (r = 6), we can calculate the area of the circle using the formula: A = πr^2.
Substitute r = 6 into the formula:
A = π(6)^2
A = π * 36
A = 36π
Therefore, the area of the circle is 36π square units.

The correct chart for a circle with a radius of 5 cm would be:
5 cm 31.4 cm 78.5 cm^2
This is because the circumference of a circle with a radius of 5 cm is 2πr = 2 * 3.14 * 5 = 31.4 cm (rounded to the nearest tenth), and the area of the circle is calculated as πr^2 = 3.14 * 5^2 = 78.5 cm^2, which corresponds to the values in the correct chart.
5 cm 31.4 cm 78.5 cm^2
This is because the circumference of a circle with a radius of 5 cm is 2πr = 2 * 3.14 * 5 = 31.4 cm (rounded to the nearest tenth), and the area of the circle is calculated as πr^2 = 3.14 * 5^2 = 78.5 cm^2, which corresponds to the values in the correct chart.
