Answer:

question 19 = no solution because not enough information

question 20 = 18 for volume

Step-by-step explanation:

question 19:

cylinder formula

surface A =2πrh+2πr2

2π times 9 times 7 + 2π times 9 times 2

SA = 508.938009882

volume equals 395.840674352

question 20:

biggest one,

4h﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4

V=18 IS the volume

The solution set of the inequality x ≥ - 4 using set builder notation and interval notation is {x | x ∈ Z, - 4 ≤ x ≤ ∞ } and [ - 4, ∞ ) respectively.

An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way.

A set can be represented by its elements or the properties that each of its members must meet can be described using set-builder notation.

Interval Notation: A set of real numbers known as an interval contains all real numbers that fall inside any two of the set's numbers.

Consider the inequality,

x ≥ - 4

In the number line, the value of x is equal to and greater than - 4 increasing to infinity.

Therefore,

The solution set using the set builder notation is:

{x | x ∈ Z, - 4 ≤ x ≤ ∞ }

The solution set of the inequality using the interval notation is:

[ - 4, ∞ )
