Cylinder and cone volumes
That the students can obtain the volume of cylinders and cones.
As you could see on the previous activity, the flat development of a cone is made
up of a circle and a circular sector; in the latter, the length of the arc is equal to the
length of the circumference of the base and the radius is the generatrix of the
cone
Make a final review of the characteristics of the cones by studying their elements
Finish answering pages 376 and 377. Link this information with the one you
worked on in the task
Now let´s watch Rotation of figures on page 378
And Flat cylinder developments on page 379 380

Instructions: carry out the exercise in your notebook and take a photo of them
(solved) the headings of your notebook should be very clear and send the photos
from book and notebook to the email itsmeroger@hotmail.com
You have to work sphere 22 on your math book
In the next section of this sequence, you will discover how to construct the flat
developments of a cone. Carefully analyze the relationship between the length of
the radius, the height of the cone and the generatrix, since only two of the three
values are indicated below and you should calculate the missing one
Begin Looking at the flat developments and answer the questions. On Pages 373.
