Area for circle is  πr² so πr² =28.26 and we can sub 3.14 as pi
3.14*r²=28.26 we can divide by 3.14 to get r² on it's own
r²=28.26/3.14
then we root both sides to get r on it's own
28.26/3.14=9 √9=3
and the diameter is double the radius 3*2=6 so the diameter is 6

disa [49]

Answer:

y = -1/2 | x+3|

Step-by-step explanation:

y = f(x + C)  C > 0 moves it left

                 C < 0 moves it right

y = Cf(x)   C > 1 stretches it in the y-direction

                0 < C < 1 compresses it

y = −f(x)  Reflects it about x-axis

Our parent function is

f(x) = |x|

We want it 3 units left

y = f(x + 3)

y = |x+3|

Then reflected across the x axis

y = −f(x)

y = -|x+3|

Then shrink by 1/2 vertically

y = Cf(x)

y = -1/2 | x+3|
