1,400 I think :D Hope I helped!
So each book is an average of 2.8 cm
so 120 divided by each book=number of books
120/2.8=42.85
round down since you can't fit .85 of a book on a shelf
the answer is 42 books
<u>Given</u>:
Given that the radius of the circle is 9 units.
The measure of the angle JHG is 160°
We need to determine the area of the shaded sector of the circle.
<u>Area of the circle:</u>
The area of the circle can be determined using the formula,
where r is the radius
Substituting r = 9 and , we get;
Simplifying, we get;
Thus, the area of the shaded sector of the circle is 36π units²
Hence, Option a is the correct answer.
