A fact family is a group of math facts using the same numbers. In the case of addition/subtraction, you use three numbers and get four facts. For example, you canform a fact family using the threenumbers 10, 2, and 12: 10 + 2 = 12, 2 + 10 = 12, 12 − 10 = 2, and 12 − 2 = 10.

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
