The formula for the circumference of a circle is C = 2πr, where r is the radius.
Thus, the fencing required to enclose a circular garden with a radius of 30 meters would be:
C = 2π(30)
C = 60π
Rounding to the nearest tenth, the answer is:
C ≈ 188.5 meters
Express the required calculation in terms of pi
and then round to the nearest tenth.
