4

Step-by-step explanation:

The given equation of circle is:

Equating it with:

We find:

Radius of the circle = 2 units

Therefore,

Diameter of the circle = 2*2= 4 units

5/6

step-by-step explanation:

if i remember correctly with perpendicular stuff you just take away the negative

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
