Find the circumference of the circle. Use 3.14 for π. Round to the nearest hundredth, if necessary.
7 in.
The circumference of the circle is about
inches.
Looks like you need to review the section on circles.
C = 2πr
To find the circumference of a circle, you can use the formula:
Circumference = π * diameter or
Circumference = 2 * π * radius
Given that the diameter of the circle is 7 inches, we can find the radius by dividing the diameter by 2:
Radius = Diameter / 2 = 7 / 2 = 3.5 inches
Now we can use the formula for circumference:
Circumference = 2 * 3.14 * 3.5 = 21.98 inches
Rounding to the nearest hundredth, the circumference of the circle is about 21.98 inches.
