Write x2 + y2 – 18x + 8y + 5 = 0 in standard form. Group terms and move the constant to the other side of the equation. x2 – 18x + y2 + 8y = –5 Determine the values that need to be added to both sides of the equation. (–18 ÷ 2)2 = 81 and (8 ÷ 2)2 = 16 Add the values to both sides of the equation. Write each trinomial as a binomial squared, and simplify the right side. What is the standard form of the equation of a circle given by x2 + y2 – 18x + 8y + 5 = 0? ()² + ()² =

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
