Answer:
31.4 in
Step-by-step explanation:
the formula for circumference is 2*
*radius. Since the diameter (which is the radius multiplied by 2) is labeled we can divide 10 by 2 to get the radius. 10/2 is 5. Since pi is an infinite number, we round it to 3.14. Then, plug in the numbers. The expression will be 2*3.14*5. 2* = 10 and 10 * 3.14 you can just move the decimal so the answer is 31.4.
The slope or also known as “m” equals 4/4 or 1 in simplified form.
Let the set of all Odd multiples of 9 between 2 and 82 be denoted by D, then, using set-builder notation,
The odd multiples of 9, 
, in the range 
form the set
Each member of the set is a term of the arithmetic progression
where the values of 
range from 0 to 4, or 
Putting these facts together, we get the result
