The circumference of circle B is 48. The circumference of circle A is 12. How many times greater is the area of circle B to the
area of circle A
1 answer:
Circumference = 2(pi)(radius)
Circle 1: 48=2(pi)(radius)
24/pi = radius
Circle 2: 12 = 2(pi)(radius)
6/pi = radius
Area = (pi)(radius)^2
Circle 1: A = (pi) (24/pi)^2
= 576 / pi
Circle 2: A = (pi) (12/pi)^2
= 144 / pi
576/144 = 4 times greater

Answer is D.Don't take out the square
Plug in -3 for x
f(-3) = 2(-3) - (-3 + 6)
f(-3) = -6 - (3)
f(-3) = -9
Solution: f(-3) = -9
