Radius is half of diameter so the diameter would be so 1.5 and 6. And circumference is 2(pi)(radius). So that's around 9.4 for the first question and 38 for the second
Answer:
There are 700 books in Library Collections.
Step-by-step explanation:
Given:
Number of historical books = 70
The equation used to find the totals number of books in library collection.
![\frac{1}{10}b = 70](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B10%7Db%20%3D%2070)
where b⇒ Total number of books in library collections.
We need to find the Total number of books in library collections.
Solution:
![\frac{1}{10}b = 70](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B10%7Db%20%3D%2070)
Now by solving the above equation we get;
First we will multiply both side by 10 we get;
![\frac{1}{10}b \times 10= 70\times 10\\\\b =700](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B10%7Db%20%5Ctimes%2010%3D%2070%5Ctimes%2010%5C%5C%5C%5Cb%20%3D700)
Hence there are 700 books in Library Collections.
