How much fencing is required to enclose a circular garden whose radius is 26

​meters?

1 answer

The formula for the circumference of a circle is C=2πr, where r is the radius. Therefore, the amount of fencing needed to enclose a circular garden with a radius of 26 meters is:

C = 2π(26)
C = 52π

Rounded to the nearest tenth, this is approximately:

C ≈ 163.4 meters.
