Mr. Zelman gave 400 books to his nephew
<em><u>Solution:</u></em>
Given that, Mr. Zelman wants to give 50% of his comic book collection to his nephew Alex
Mr. Zelman has 800 comic books
Number of books with Zelman = 800
Mr. Zelman wants to give 50% of books to Alex
Number of books given to nephew = 50 % of books of Zelman
Therefore, we have to find 50 % of 800
Thus he gave 400 books to his nephew
Hi there!
<u>FACTS</u> :
The formula for the volume of a cylinder is : V = × r² × h
<u>STEPS TO ANSWER:</u>
You have the diameter of the cylinder, which is 13cm.
In order to have the radius of the cylinder to put in our formula, you'll need to divide the diameter by 2 because the diameter is two times the radius:
13 ÷ 2 = 6.5
Now that you have the radius (6.5) and the height (24cm) of the cylinder, you can put these information in the formula and calculate de volume :
V = × r² × h
V = × <u>6.5²</u> × 24
V = × <u>42.25 × 24</u>
V = × 1,014
V = 3,185.574950......
Since you need to round your answer to the nearest tenth, which means that you will have only one decimal, the volume of the cylindrical container would be about 3,185.6cm³.
There you go! I really hope this helped, if there's anything just let me know! :)
