square inches
The area of a circle is calculated using the formula A = πr^2, where A is the area and r is the radius. In this case, the diameter is given as 10 inches. Since the radius is half the diameter, the radius would be 5 inches.
Using the formula, we can calculate the area:
A = πr^2
A = 3.14 * 5^2
A = 3.14 * 25
A = 78.5
Therefore, the area of a circle with a diameter of 10 inches is 78.5 square inches.
To find the area of a circle, you can use the formula:
Area = π * r^2
where π is a constant approximately equal to 3.14, and r is the radius of the circle.
Given that the diameter of the circle is 10 inches, we can find the radius by dividing the diameter by 2:
radius = diameter / 2 = 10 inches / 2 = 5 inches
Now, we can substitute the radius into the formula:
Area = 3.14 * (5 inches)^2 = 3.14 * 25 square inches = 78.5 square inches
Therefore, the exact area of the circle is 78.5 square inches.
To find the area of a circle with the diameter, you can use the formula:
Area = π * (radius)^2
First, let's find the radius of the circle. The diameter is given as 10 inches, which means the radius is half of that. So, the radius = 10 inches / 2 = 5 inches.
Now, we can substitute the value of the radius into the area formula:
Area = 3.14 * (5 inches)^2
Calculating:
Area = 3.14 * 25 square inches
The exact area of the circle is 78.5 square inches.
