R = 13.1
so
<span>diameter = 13.1 x 2 = 26.2 km
</span>circumference = 2 pi r = 26.2 pi km
or
circumference = 26.2 x 3.14 = 82.27 km

16-4=12 12-4=8 8-4=4
Answer:
(0,1) and (4,17)
Step-by-step explanation:
y=2x² - 4x + 1
y = 4x + 1
2x² - 4x + 1 = 4x +1
2x² - 4x = 4x
2x² - 8x =0
2x(x-4) = 0
x=0, or x=4
x=0, y=4x+1=4*0 + 1 = 1 (0,1)
x=4, y=4x+1 = 4*4 +1 = 17 (4, 17)
