Answer:

Step-by-step explanation:

hello :

Completing The Square x²-4x-2= (x²-4x+4)-4-2 = (x-2)²-6

the vertex is : (2 , -6)

now calculate the solutions : (x-2)²-6 =0

(x-2)²= 6 means : x-2 =√6 or x-2 = -√6

x = 2+√6 or x = 2-√6

The exact circumference of a circle is 34π meters. What is the approximate area of the circle? Use 3.14 for π. Round to the near

LiRa [457]

Answer:

A = 907.46 $m^{2}$

Step-by-step explanation:

C = πd

34π = πd

d = 34

r = 17

A = $\pi r^{2}$ = 3.14( $17^{2}$ ) = 3.14(289) = 907.46 $m^{2}$
