Answer:

86 books

Step-by-step explanation:

A stack of books is 43 inches tall.

Each book is \frac{1}{2} inch thick.

To find the number of books in tha stack, divide the height of the stack by the height of the book:

43:\dfrac{1}{2}

The division by the fraction \frac{1}{2} is equivalent to the multiplication by the fraction \frac{2}{1}, so

43:\dfrac{1}{2}=43\cdot \dfrac{2}{1}=43\cdot 2=86

A conical perfume bottle has a radius of 3.2 centimeters and a height of 3.9 centimeters.
ioda

For this case, we must find the volume of the perfume bottle, given by the volume of a cone.

V = \frac {\pi * r ^ 2 * h} {3}

Where:

r: It's the radio

h: It's the height

Substituting the values:

V = \frac {3.14 * (3.2) ^ 2 * 3.9} {3}\\V = \frac {125.39904} {3}\\V = 41.79968 \ cubic \ centimeters

Round off:

V = 41.80 \ cubic \ centimeters

Thus, the bottle contains 41.80 cubic centimeters of perfume

Option C
