1 answer:
Answer:
Step-by-step explanation:
equation of a line
y - y1 = m(x -x1)
where (x1, y1) is a point on the line and m is the slope
since it is parallel to the line 3x + y = -7, put in y = mx + b form to find the slope
y = -3x - 7, therefore m = -3
y - 1 = -3(x - 2)

Answer:
69.1 cm
Step-by-step explanation:
Circumference of a circle
c = 2πr
Half of that would be a semi-circle
c = πr
c = π * 22
c = 69.115038379
Rounded
69.1 cm
