meters?
Answers
The formula for the circumference of a circle is C = 2πr, where r is the radius.
So, the amount of fencing required would be:
C = 2π(19)
C = 38π
Rounding to the nearest tenth:
C ≈ 119.4 meters
So, the amount of fencing required would be:
C = 2π(19)
C = 38π
Rounding to the nearest tenth:
C ≈ 119.4 meters
