Question

Kiyo used wire fencing to form a border around a circular region in his backyard. If the radius of the circular region was 5 yards, what was the total length of the border, rounded to the nearest tenth of a yard?.

Answer 1

The formula for circumference is πd.

Diameter is 2r.

5 x 2 = 10

Use 3.14 for π.

10 x 3.14 = 31.4 yards

Hope this helps!
