Answer:
Bill needs 7.85 meters of fence to cover the edges of the circle garden.
Step-by-step explanation:
Since we know the diameter of the garden is 2.5 meters, we can either do the formulas 2πr, which R= the radius, which is half the diameter. So we take 2 x π which is 6.28, then multiply that by the radius. Half of 2.5 is 1.25, which equals the radius. 1.25 x 6.28 = 7.85.
