63 yards.

Step-by-step explanation:

The circumference of a circle is its diameter multiplied by the constant pi.. We are told to use and , so we rearrange:

We find that .

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
