Does the graph shown below represent y as a linear function of r? ข 9 8+ 7+ 6+ 5+ 4+ 3+ 2 1+ -9-8-7 + + 6-5-4-3-2 1 2 3 1 5 6 7 8 9 - 4 - 5 -6 --7 -8​

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

y∈r, 8> y≥0

hope i !

p.s the first bit only matters if you know what that means.

p.p.s brainliest would really
