Answer:
3rd option
Step-by-step explanation:
Since the centre of dilatation is at the origin then multiply the coordinates by 
K (- 3, 9 ) → K' (- 3( ), 9( ) ) → K' (- 1, 3 )
L (- 9, 0 ) → L' (- 9( ), 0 ( ) ) → L' (- 3, 0 )
M (2, - 8 ) → M' (2 ( ), - 8 ( ) ) → M' ( 
, - 
)
N (6, 4 ) → N' (6 ( ) , 4 ( ) ) → N' ( 2, 
)

Answer:
7.85 m (3 significant figures)
Step-by-step explanation:
Formula: arc length = 
The radius of a circle is half the diameter, so r = 10 ÷ 2 = 5
Therefore, arc length = 2 x 
x 5 x 
= 
= 7.853981634...
= 7.85 m (3 significant figures)
A right angle has 90 degrees, so 90 divided by 6 = 15 degrees
