The formula for calculating the area of a circle is:
r²π
So, the area of a circle with a diameter of 6 inches (with a radius of 3 inches) is:
3²π = 9π ≈ 28.2743 in²

The area of a circle with a diameter of 6.5 is: 33.18 square units.
The area is 28.274 square meters.
The area of a circle is calculated using the formula A = πr^2, where A is the area and r is the radius of the circle. Since the diameter of the circle is 12 inches, the radius would be half of that, which is 6 inches. Converting inches to feet (1 foot = 12 inches), the radius would be 0.5 feet. Plugging this into the formula, the area of a 12-inch circle would be approximately 0.785 square feet.
If a circle has a circumference of 6 inches the diameter is: 1.91 inches (circumference divided by Pi = diameter).
Since circumference equals pi times the diameter, if the diameter of a circle is 6, then its circumference is going to be pi times 6 or 6 pi.
