Answer:
Step-by-step explanation:
Given
See attachment for farm
Required
The cost of fencing the farm
First, calculate the radius of the farm.
The radius is represented with AC.
So, we have:
---- distance formula
Hence:
--- radius
Calculate the circumference of the circle
If 1 yard costs $30, 31.4 yards will cost:
Subtraction Property of Equality
you should subtract both side with 7 first.
C
The length of arc AC (L) is calculated as
L = circumference of circle × fraction of circle
= 2πr ×
= 2π × 12 ×
= 2π × 5
= 10π ≈ 31.42 → C
17442
120x4= 480
17922-480=
