Grade 6 Area Perimeter Review Quiz

There is a thatquiz waiting that has mixed questions on area and perimeter. Read each question carefully so you know what is being asked. For area of a rectangle multiply the length and the width.

For perimeter, add all the sides (even if they are not marked).

Grade 6: Perimeter and Area

https://www.khanacademy.org/math/geometry/hs-geo-foundations/hs-geo-area/v/perim…

This video describes the concepts of perimeter and area.

You should know how to :

find the perimeter of any shape. (add the length of the sides)
find the area of a rectangle ( multiply the length and the width) A= L X W
a formula, such as A= L X W, is short efficient way to express the instructions to calculate a concept

There will be a thatquiz where you can practice finding the perimeter and area.

Grade 8: Total Surface area of CYLINDERS

Happy Monday!!

A few notes for review:

total surface area is the amount of surface on the outside of an object. "What amount of material would it take to cover the object. "
for TSA of Rectangular Prisms you can find the area of each rectangle(6 of them) and add them up
for TSA of Triangular Prisms you can find the area of the 3 rectangles and the two triangles and add them up
radius of a circle is the distance from the center of the circle to the outside of the circle
diameter of a circle is the distance from one side of the circle through the center to the other side. It's twice the radius.
circumference is the distance around the outside of the circle.
pi = 3.14 as an approximation
for a right cylinder you can find the area of the 2 circles (A = pi X r X r ) * usually written as A= pi r²and a rectangle. Rectangles have 2 dimensions (length and width) one dimension of the rectangle will be the height of the cylinder. The other will be the circumference of the circle( circumference= pi X diameter) c= pi d. Multiply the 2 dimensions to find the area of the rectangle. Finally add the areas of the 2 circles and the rectangle to find the total surface area!
There will be a video posted dealing with this concept.
Use paper, pencil and calculator. Staying organized is key in solving these problems. Draw and label each part of the shape. *Remember diameter is 2 times the radius.
