Solve for the variable a in this equation. c = 8πab

a = c / 8πb

Step-by-step explanation:

To solve for the variable a or to make a subject of the formular, we divide bothside by 8πb

c /8πb = 8πab/8πb

c / 8πb = a

a = c / 8πb

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
