Answer:
r = 3
Step-by-step explanation:
The formula of a volume of a cone
V= 1/3 pie r^2 H
r - radius
H - height
We have V = 12π in³ and H = 4 in. Substitute:
4 times 1 = 4
and 7 times 8 = 56
so 4/56 is your answer. Your teacher prolly wants you to simplify that answer.

Answer:
the two expressions are equivalent.
Step-by-step explanation:
We know that f(x)= 3x-7 and g(x)= -2x+5, therefore:
f(x) - (-g(x)) = 3x-7 - ( +2x-5) = 3x - 7 - 2x + 5 = x -2
f(x) + g(x) = 3x-7 -2x + 5 = x - 2
Therefore, f(x) - (-g(x)) is equivalent to f(x) + g(x).
Another way to check that the two expressions are equivalent is by solving the parenthesis:
f(x) - (-g(x)) → f(x) + g(x)
Therefore, the two expressions are equivalent.
