I think I know the answer but let me check it before I answer u
Answer:
C = 3pi cm or approximately 9.42 cm
Step-by-step explanation:
The formula for circumference of a circle is given by
C = pi *d
C = pi *3
C = 3pi
or approximately
C = 3*(3.14)
=9.42 cm
The inequality begins with the flat fee of $25. We then add the $13 per day for insurance as 13<em>d</em>, where <em>d</em> is the number of days. This gives us the expression
25 + 13<em>d</em>. Since he only has $121, we must use less than or equal to for our inequality; he can't spend any more than $121, but he can spend any number below it up to that number. This gives us
25 + 13<em>d</em> ≤ 121<em />

Step-by-step explanation:
The U and inverted U symbols, ∪ and ∩, are mathematical symbols used to denote union or intersection, respectively. For example, when a rational algebraic equation is graphed, there may be some points where the equation is undefined. Visually, we see it as breaks or discontinuities. We use the ∪ symbol to express union. For example, {-∞,2)∪(4,+∞). That means that the graph passes at all x values except x=3.
The ∩ symbol is used for intersection of two lines, for instance. When equation A and equation B are graphed, they can intersect at points (x,y). It is therefore expressed as: A∩B = (x,y).
