If the radius of a circle is four inches the diameter, circumference and area are:Diameter = 8 inchesCircumference = 25.13 inchesArea = 50.27 square inches
Take "pi" times the diameter of the circle. Pi = 3.14159 (ALWAYS) If circle has a diameter of 10cm, circumference 31.41cm If circle has a radius of 2inches, the circumference is 12.57 inches. (radius = 2, diameter = 4)
The idea is to divide the circumference by pi.
Divide the circumference by the number pi, which is approximately 3.14.
To find the diameter of a circle with a 3-inch circumference, you can use the formula C = πd, where C is the circumference, π is pi (approximately 3.14159), and d is the diameter. Plugging in the given circumference of 3 inches, the formula becomes 3 = πd. Solving for d, you get d ≈ 0.955 inches. Therefore, the diameter of a circle with a 3-inch circumference is approximately 0.955 inches.
If the diameter of a circle is 4 inches the circumference will be about 12.57 inches. (d x Pi = C)
A circumference of 12.57 inches.
Diameter = 1.273 inches.
The circumference of a 4-inch diameter circle is: about 12.57 inches. (diameter x pi = circumference).
A circle with a radius of 4 inches has a circumference of 25.13 inches.
about 12.57 inches
Circumference of the circle: 4 times pi in inches
Circumference of circle: 4 times pi in inches
circumference = 4*pi inches
yes
If the radius of a circle is four inches the diameter, circumference and area are:Diameter = 8 inchesCircumference = 25.13 inchesArea = 50.27 square inches
Multiply the radius by 2 to get the diameter. Then multiply the diameter by pi to get the circumference. Example: If radius = 2 inches, diameter = 4 inches circumference = 4 x pi = 4 (3.1416) or about 12.57 inches
