1 = scale factor of 2 and x =3
Answer:
im pretty sure the answer is -12
Step-by-step explanation:
0=-2x+6
-6=-2x
x=3
-4×3=-12
The radius is found from
... A = πr²
... r = √(A/π) = √(154/π) m ≈ 7.00 m
The circumference is then
... C = 2πr = 2π(7.00 m) ≈ 43.99 m
The circumference is about 44.0 m.
I believe the answer would be 70 but make sure just in case.
