The area of a circle can be calculated using the formula:
A = πr²
Where A is the area, π (pi) is approximately 3.14, and r is the radius of the circle.
In this case, the diameter of the circle is given as 3 inches. To find the radius, we simply divide the diameter by 2:
r = diameter / 2 = 3 inches / 2 = 1.5 inches
Now that we have the radius, we can plug it into the area formula:
A = π(1.5 inches)²
Calculating the square of the radius gives us:
A = π(2.25 inches²)
Now, multiplying by π:
A ≈ 3.14 × 2.25 inches²
A ≈ 7.065 inches²
Therefore, the area of the circle is approximately 7.07 square inches.
