Answer:
The total length of the border is 31.4 yards rounded to the nearest tenth of a yard
Step-by-step explanation:
The formula of the circumference of a circle is C = 2πr, where r is the radius of the circle
Jason used wire fencing to form a border around a circular region in his back yard
<em>That means the length of the wire is equal to the circumference of the circular region</em>
∵ The radius of the circular region was 5 yards
∴ r = 5 yards
∵ C = 2πr
- Substitute r by 5
∴ C = 2π(5)
∴ C = 31.41592654 yards
- Round it to the nearest tenth of a yard
∴ C = 31.4 yards
∵ The length of the wire is equal to the circumference of
the circular region
∴ The length of the wire is 31.4 yards
The total length of the border is 31.4 yards rounded to the nearest tenth of a yard
