Answers
GPT 3.5
To find the circumference of a circle, you can use the formula:
Circumference = 2 * π * radius
Given that the radius of the circle is 1.7 ft, we can plug this into the formula:
Circumference = 2 * π * 1.7
Circumference = 2 * 3.14159 * 1.7
Circumference = 10.6576 ft
Therefore, the circumference of the circle is approximately 10.7 ft when rounded to the nearest tenth.
Circumference = 2 * π * radius
Given that the radius of the circle is 1.7 ft, we can plug this into the formula:
Circumference = 2 * π * 1.7
Circumference = 2 * 3.14159 * 1.7
Circumference = 10.6576 ft
Therefore, the circumference of the circle is approximately 10.7 ft when rounded to the nearest tenth.
The circumference of a circle is 19piπ ft. Find its radius, in feet.
GPT 3.5
To find the radius of a circle given the circumference, you use the formula:
Circumference = 2 * π * radius
Given that the circumference is 19π ft, we can set up the equation and solve for radius:
19π = 2π * radius
19π = 2πr
Divide both sides by 2π to isolate the radius:
radius = 19π / 2π
radius = 9.5 ft
Therefore, the radius of the circle is 9.5 ft.
Circumference = 2 * π * radius
Given that the circumference is 19π ft, we can set up the equation and solve for radius:
19π = 2π * radius
19π = 2πr
Divide both sides by 2π to isolate the radius:
radius = 19π / 2π
radius = 9.5 ft
Therefore, the radius of the circle is 9.5 ft.
The circumference of a circle is 9piπ m. Find its diameter, in meters.
GPT 3.5
To find the diameter of a circle given the circumference, you can use the formula:
Circumference = π * diameter
Given that the circumference is 9π m, we can set up the equation and solve for diameter:
9π = π * diameter
9 = diameter
Therefore, the diameter of the circle is 9 meters.
Circumference = π * diameter
Given that the circumference is 9π m, we can set up the equation and solve for diameter:
9π = π * diameter
9 = diameter
Therefore, the diameter of the circle is 9 meters.
The diameter of a circle is 10 m. Find its area in terms of piπ.
GPT 3.5
The formula to find the area of a circle is:
Area = π * (radius)^2
Given that the diameter of the circle is 10 m, we can find the radius by dividing the diameter by 2:
radius = diameter / 2
radius = 10 / 2
radius = 5 m
Now, we can plug the radius into the formula:
Area = π * (5)^2
Area = 25π m^2
Therefore, the area of the circle is 25π square meters.
Area = π * (radius)^2
Given that the diameter of the circle is 10 m, we can find the radius by dividing the diameter by 2:
radius = diameter / 2
radius = 10 / 2
radius = 5 m
Now, we can plug the radius into the formula:
Area = π * (5)^2
Area = 25π m^2
Therefore, the area of the circle is 25π square meters.
The radius of a circle is 15 cm. Find its area in terms of piπ.
GPT 3.5
To find the area of a circle, you use the formula:
Area = π * (radius)^2
Given that the radius of the circle is 15 cm, we can plug this into the formula:
Area = π * (15)^2
Area = π * 225
Area = 225π
Therefore, the area of the circle is 225π square centimeters.
Area = π * (radius)^2
Given that the radius of the circle is 15 cm, we can plug this into the formula:
Area = π * (15)^2
Area = π * 225
Area = 225π
Therefore, the area of the circle is 225π square centimeters.
The diameter of a circle is 14 m. Find its area to the nearest whole number.
GPT 3.5
To find the area of a circle when the diameter is given, you first need to find the radius by dividing the diameter by 2.
Radius = Diameter / 2
Radius = 14 m / 2
Radius = 7 m
Now, you can use the formula to find the area of the circle:
Area = π * (Radius)^2
Area = π * (7)^2
Area = π * 49
Area ≈ 153.94
Rounding to the nearest whole number, the area of the circle is 154 square meters.
Radius = Diameter / 2
Radius = 14 m / 2
Radius = 7 m
Now, you can use the formula to find the area of the circle:
Area = π * (Radius)^2
Area = π * (7)^2
Area = π * 49
Area ≈ 153.94
Rounding to the nearest whole number, the area of the circle is 154 square meters.
