What is the approximate area of the circle shown? use 3.14 to approximate pi. round your answer to the nearest whole number. circle diameter is 18

The area of the circle is 254 square unit. ( approx )

Step-by-step explanation:

Given,

The diameter of circle = 18 unit,

⇒ The radius of the circle = = 9 unit,

Since, the area of a circle,

Where r is the radius of the circle,

Thus, the area of the circle is,

      ( = 3.14 )

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

x coordinate is none
