Step-by-step explanation:
Answer:a) 84π b) 109.2π
Step-by-step explanation:
The formula to find this is v=πr^2h/3
r=d/2. so the radius (r) is 6 because you have to divide the diameter (12) by 2. and the height is 7. so, 6^2=36 and 36x7=252.
252/3=84
and because the question is asking for the EXACT value, you need to just put the pi symbol next to it. Final answer for a is 84π
B) you need to find 30% of 84, which is 25.2 and add it to 84, and you will get 109.2! Final answer is 109.2π.

Answer:
(c) g(x) = (x/4)^2
Step-by-step explanation:
The graph of f(x) is expanded horizontally by a factor of 4. That means ...
g(x) = f(x/4) . . . . transformation for horizontal expansion by 4
g(x) = (x/4)^2
