What is the approximate difference in the circumference of a circle with a radius of 4 ft and the circumference of a circle with a radius of 6 ft?
2 ft
6 ft
13 ft
20 ft
The circumference of a circle is calculated using the formula C = 2πr, where r is the radius of the circle.
For a circle with a radius of 4 ft:
Circumference = 2π(4) = 8π ft ≈ 25.13 ft
For a circle with a radius of 6 ft:
Circumference = 2π(6) = 12π ft ≈ 37.70 ft
The approximate difference in the circumferences of the two circles is:
37.70 ft - 25.13 ft ≈ 12.57 ft
Therefore, the approximate difference in the circumferences of the two circles is 13 ft.
