Answer:
25.12ft
Step-by-step explanation:
C=2πr
C = 2(3.14)(4)
C = 25.12ft
25.12
The circumference of a circle is equal to . So, to find the circumference plug in 4 for r and solve the expression. , where equals 3.14 is 25.12.
y=-2/3x+20/3
m=(y2-y1)/(x2-x1)
m=(4-6)/(4-1)
m=-2/3
y-y1=m(x-x1)
y-6=-2/3(x-1)
y=-2/3x+2/3+6
y=-2/3x+2/3+18/3
18 = 3.2
B. 100 degrees
