impatient much?
Once is enough, thank you.

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.
1. For the circle with a radius of 6 inches:
A = π(6)^2 = 36π square inches
Rounded to the nearest square unit: 36π square inches ≈ 113 square inches
2. For the circle with a radius of 10 meters:
A = π(10)^2 = 100π square meters
Rounded to the nearest square unit: 100π square meters ≈ 314 square meters
3. For the circle with a radius of 25 centimeters:
A = π(25)^2 = 625π square centimeters
Rounded to the nearest square unit: 625π square centimeters ≈ 1963 square centimeters
4. For the circle with a diameter of 30 feet:
The radius of a circle is half of its diameter, so the radius would be 30/2 = 15 feet.
A = π(15)^2 = 225π square feet
Rounded to the nearest square unit: 225π square feet ≈ 706 square feet
5. For the circle with a diameter of 22 centimeters:
The radius of a circle is half of its diameter, so the radius would be 22/2 = 11 centimeters.
A = π(11)^2 = 121π square centimeters
Rounded to the nearest square unit: 121π square centimeters ≈ 380 square centimeters
6. For the circle with a diameter of 15 kilometers:
The radius of a circle is half of its diameter, so the radius would be 15/2 = 7.5 kilometers.
A = π(7.5)^2 = 56.25π square kilometers
Rounded to the nearest square unit: 56.25π square kilometers ≈ 176 square kilometers
Note: π is a mathematical constant, commonly approximated as 3.14159.
