Area=pi times radius^2 so
if area=4pi=pi times r^2
4 times pi=r^2 times pi
divide both sdies by pi
4=r^2
square root
2=radius since legnth cannot be negative
radius=1/2 diamters
2 radius=diameter
2(2)=diameter=4
diameter=4
Answer:
Step-by-step explanation:
Please use " ^ " to indicate exponentiation: f(x) = x^2 and g(x) = (3x)^2.
g(x) can be rewritten as 9x^2.
The graph of g(x) is only one ninth as wide as that of f(x).
Next time please share the possible answer choices. Thank you.

Answer:
b
Step-by-step explanation:
Answer: 33
Step-by-step explanation:
(f of g)(2) = f(g(2))
g(2) = -2(2) = -4
f(-4) = (-4)^2 - 3(-4) + 5 =
16 - - 12 + 5 =
16 + 17 =
33
