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

A student claims that 3(3x + 2) + 5 - 4x is equivalent to 5x + 7; however, the student is incorrect. The student's work is shown
Yuliya22 [10]

Answer:

The answer to your question is below

Step-by-step explanation:

                        3(3x + 2) + 5 - 4x =  5x + 7

Step 1: 3(3x + 2) + 5 - 4x           There is no error here, only wrote the

                                                    polynomial again

Step 2: 9x + 2 + 5 - 4x                He forgot to multiply 3 x 2 = 6

                                                     9x + 6 + 5 - 4x

Step 3: 9x - 4x + 2 + 5               He simplified like terms

Step 4: 5x + 7                              but is incorrect due to his mistake

                                                     The right answer should be 5x + 11

Find the value of x trigonometry
Luden [163]

Step-by-step explanation:

sin30° = x/14

1/2 = x/14

1/2 × 14 = x

x = 7

cos30° = y/14

squareroot3/2 = y/14

0.866 = y/14

y = 0.866 × 14

y = 12.124
