Answer:
1. 6pi or 18.84cm
2. 20pi or 62.8cm
3. 13pi or 40.82cm
4. 9.5pi or 29.83cm
5. You calculate the circumference of a circle with the expression 2pi(r). r stands for the radius. You can also use pi(d), or pi x diameter.
7. You would use 2pi(r) to find the circumference of a circle when given the value of the circle's radius.
8. You would use pi(d) to find the circumference of a circle when given the value of the circle's diameter.
Answer: The options are kinda weird
But the solution to x - 12.5 = 17 is x = 29.5, so whichever equation you plug this into is correct is the right equation...
-4 times -2 equals 8.
8 times -1 equals -8.
Therefore, the point on your number line that is on -8 is your answer!
Answer:
Andrew has been in the book club for 18 months.
Step-by-step explanation:
The number of books already read by Andrew = 13 books
He reads 1 book each month after joining the book club.
Number of books he has read after joining the club = 31 books
Number of books read after joining the Club
= Total books Read - Books read beforehand
= 31 books - 13 books
= 18 books
So, the number of books Andrew read within the club = 18 books
Now, as Andrew read 1 book per month
⇒ Andrew reads 18 books in 18 x ( 1 Month) = 18 Months
Hence, Andrew has been in the book club for 18 months.
C and B
-55 minus -35
