Answer:

Its wrong, you should divide the amount of the objects you have by the amount of students

Step-by-step explanation:

This "hourglass" consists of two identical solid cones contained in a right cylinder. The cylinder is 12 cm tall and the circumf
ratelena [41]

Volume is a three-dimensional scalar quantity. The volume of the space between the cylinder and the two cones is 1184.43183 cm³.

<h3>What is volume?</h3>

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

Given the circumference of the base is 61 cm, therefore, the radius of the base will be,

Circumference = 61 cm

2πR = 61

R = 61/(2π) = 9.70845 cm

The volume of the cylinder(Outside shell) can be written as,

Volume = πR²×H

             = π× (9.70845)² ×12

             = 3553.29326 cm³

The volume of the two identical cones will be,

The volume of the cone = 2× (1/3) × π × R² × H

                                        = (2/3)×π×(9.70845²)×12

                                        = 2368.86143 cm³

The volume of the space between the cylinder and the two cones is,

The volume between space = 3553.29326 cm³ -  2368.86143 cm³

                                                = 1184.43183 cm³

Hence, the volume of the space between the cylinder and the two cones is 1184.43183 cm³.

Follow the steps and it will help on all the problems and it should help you out.

Step-by-step explanation:

  1. You can make equivalent fractions by multiplying or dividing both top and bottom by the same amount.
  2. You only multiply or divide, never add or subtract, to get an equivalent fraction.
  3. Only divide when the top and bottom stay as whole numbers.

Basile [38]
Notice the picture below

what we have, is really an angle, encroached by two sides

thus, use the Law of Cosines

\bf \textit{Law of Cosines}\\ \quad \\&#10;c^2 = {{ a}}^2+{{ b}}^2-(2{{ a}}{{ b}})cos(C)\implies &#10;c = \sqrt{{{ a}}^2+{{ b}}^2-(2{{ a}}{{ b}})cos(C)}\\\\&#10;-----------------------------\\\\&#10;\textit{so the distance "c" from the airplane to the airport}\\&#10;\textit{using angle C, and the sides "a" and "b"}&#10;\\\\\\&#10;c=\sqrt{150^2+170^2-(2\cdot 150\cdot 170)cos(49.17^o)}\qquad&#10;\begin{cases}&#10;a=150\\&#10;b=170\\&#10;C=49.17^o&#10;\end{cases}
