Answer:
The solution is the interval  (-∞,5]
Step-by-step explanation:
we have

The solution is the interval -----> (-∞,5]
All real numbers less than or equal to 5
In a number line the solution is the shaded area at left of x=5 (close circle)
see the attached figure

Answer:
268.0 in²
Step-by-step explanation:
refer to attached graphic as reference
volume of cone, V = (1/3) πr²h
in our case, we are given r = 4" and h = 16"
substituting this into equation:
V = (1/3) πr²h
=  (1/3) ·(3.14) · (4)²· (16)
= 267.94667 in²
= 268.0 in² (nearest tenth)
