Circumference & Area Of Circles Practice Answers
Answers
GPT 3.5
1. What is the circumference of a circle with a radius of 5 units?
Circumference = 2 * π * radius
Circumference = 2 * π * 5
Circumference = 10π units
2. What is the area of a circle with a diameter of 8 units?
Radius = diameter / 2
Radius = 8 / 2
Radius = 4 units
Area = π * radius^2
Area = π * 4^2
Area = 16π square units
3. What is the circumference of a circle with a diameter of 12 units?
Radius = diameter / 2
Radius = 12 / 2
Radius = 6 units
Circumference = 2 * π * radius
Circumference = 2 * π * 6
Circumference = 12π units
4. What is the area of a circle with a circumference of 24π units?
Radius = Circumference / (2 * π)
Radius = 24π / (2 * π)
Radius = 12 units
Area = π * radius^2
Area = π * 12^2
Area = 144π square units
5. What is the circumference of a circle with an area of 36 square units?
Radius = √(Area / π)
Radius = √(36 / π)
Radius = √(36) = 6 units
Circumference = 2 * π * radius
Circumference = 2 * π * 6
Circumference = 12π units
Circumference = 2 * π * radius
Circumference = 2 * π * 5
Circumference = 10π units
2. What is the area of a circle with a diameter of 8 units?
Radius = diameter / 2
Radius = 8 / 2
Radius = 4 units
Area = π * radius^2
Area = π * 4^2
Area = 16π square units
3. What is the circumference of a circle with a diameter of 12 units?
Radius = diameter / 2
Radius = 12 / 2
Radius = 6 units
Circumference = 2 * π * radius
Circumference = 2 * π * 6
Circumference = 12π units
4. What is the area of a circle with a circumference of 24π units?
Radius = Circumference / (2 * π)
Radius = 24π / (2 * π)
Radius = 12 units
Area = π * radius^2
Area = π * 12^2
Area = 144π square units
5. What is the circumference of a circle with an area of 36 square units?
Radius = √(Area / π)
Radius = √(36 / π)
Radius = √(36) = 6 units
Circumference = 2 * π * radius
Circumference = 2 * π * 6
Circumference = 12π units
