The formula for the area of a circle is A = πr², where r is the radius.
Plugging in the given radius of 7 inches:
A = π * 7²
A = 49π
To round to the nearest tenth, we can approximate the value of π to 3.14:
A = 49 * 3.14
A ≈ 153.86
Therefore, the area of the circle with a radius of 7 inches is approximately 153.9 square inches.

To find the area of a circle, you can use the formula A = πr^2, where A represents the area of the circle and r represents the radius. Given that the radius is 7 inches, we can substitute this value into the formula:
A = π(7^2)
Calculating the square of the radius:
A = π(49)
To find the area rounded to the nearest tenth, we need to multiply the result by π and round it. The value of π is approximately 3.14.
A ≈ 3.14(49)
A ≈ 153.86
Rounding to the nearest tenth:
A ≈ 153.9 square inches
Therefore, the area of a circle with a radius of 7 inches is approximately 153.9 square inches.
To find the area of a circle, you can use the formula: A = πr^2, where A is the area and r is the radius of the circle.
Given that the radius of the circle is 7 inches, we can substitute the value into the formula:
A = π(7^2)
Next, calculate the value of the radius squared:
A = π(49)
Approximating the value of π to 3.14, we can further simplify:
A ≈ 3.14(49)
A ≈ 153.86
Rounded to the nearest tenth, the area of the circle is 153.9 square inches.
