Final answer:
The length of the garden edge, which is the circumference of a circle with a radius of 3 meters, is approximately 18.8 meters. The calculation uses the formula C = 2πr.
Step-by-step explanation:
To calculate the length of the garden edge, which is the circumference of a circle, we use the formula C = 2πr, where C is the circumference, π (pi) is approximately 3.14159, and r is the radius of the circle. Given that the radius of the circle is 3 meters, we substitute r with 3 meters.
The calculation would be C = 2π(3 m) = 2(3.14159)(3 m). After performing the multiplication, we find that the length of the garden edge is 18.85 meters. However, since the radius was given with a precision of one decimal point, we should limit our answer to the same precision, so the final answer is approximately 18.8 meters.
