what is the area of a circle whose daimeter is 5 in

area= PI (diameter/2)^2

2.5 * 2.5* 3.14

*=multiply

To find the area of a circle, you can use the formula A = πr^2, where A represents the area and r represents the radius of the circle.

In this case, you are given the diameter, which is the distance across the circle passing through its center. To find the radius, you need to divide the diameter by 2. Therefore, the radius (r) of the circle with a diameter of 5 inches would be 5/2 = 2.5 inches.

Now that you have the radius, you can plug it into the formula: A = π(2.5)^2.

The value of π, which is called "pi," is a mathematical constant and approximately equal to 3.14159 (you can use a more precise value if needed).

Now, calculate the area: A = 3.14159 * (2.5)^2 ≈ 19.63 square inches.

So, the area of a circle with a diameter of 5 inches is approximately 19.63 square inches.
