Answer:
r = √(V/πh)
Step-by-step explanation:
V=π*r^2*h solve for r
divide both sides by πh
V/πh = π*r^2*h/πh
Simplify
V/πh = r^2
so r = √(V/πh)
Answer:
Take 2 to the other side,
So, x = 4 - 2
Answer: x = 2
Answer:
see attachment
Step-by-step explanation:
The y-intercept is +4 for both lines, so only the third selection is appropriate. The lines appear to have a slope of magnitude less than 1, so ±1/2 seems about right.
(We expect at least one of the inequality symbols to include the "or equal to" case so there is no hole at x=0. Alas, it seems the third answer choice doesn't do that.)
