Vocabulary Altitude- a line segment perpendicular to the line containing a base of a figure and drawn from the opposite of that base Area- the number of square units it enclosures(x 2) Base of a 3 dimensional figures- the bottom or top that we multiply by Circle-a 2 dimensional shape with no angles Circumference- the distance around a circle Cone- has one circular base and one vertex Cube- a rectangular prism with 6 congruent faces Cubic Unit- a square occupied by a dog with edges one unit long -

Cylinder- 2 parallel bases that are congruent circles Diameter- a chord that passes through the center of a circle Formula- a mathematical relationship or rule expressed in symbols Height of a 3 dimensional figure- the distance from the center the base to the center of the top Hypotenuse- longest line of a triangle Pi- the ratio of a circle's circumference to its diameter 3. 14 Pythagorean theorem- shows how the legs and hypotenuse of a right triangle are related

Radius -a straight line from the center to the circumference of a circle or sphere Slant height- the height of a face to find the area of the lateral faces Solid- having 3 dimensions(length, breadth and thickness Space figure- prisms, pyramids, cylinders, cones, and spheres sphere- is a set of all points in space that are given distance from a given point called the center Surface area- is the sum of the areas of the bases and the later phases of a space figure Volume- of a three dimensional figure is the number of cubic units needed to fill it Vocabulary

Volume for cylinders only use pi when approximating Cylinders

Formula For Spheres bjks to solve, you must multiply pi or the radius squared by 4 and divide it by 3 in

Formula For Cones To find Slant Height a(square)+b(square)= c(square) -C(squared ) is always the one you need to find -Plug in the slanted height for either A or B -Plug in the radius for either A or B - Add both together and YOu found the height

Formula For Composite Shapes diameter= 6 radius=3 cones=one third 3 squared sphere- four thirds radius =3 answer=volume of sphere is 36 volume cone =13

Volume Of Cylinders nn Volume for cylinders pi radius squared height

Volume Of Cones CCFU- find the exact volume of an ice cream cone with radius of 2 and a height of 6

Volume of Spheres Volume of a sphere aka circle is four thirds pi radius cubed (3) because it is 3 dimensional figure.

Volume Of Composite Shapes CFU-find the volume of a circular popsicle with a square holder. Sphere= radius= 7 and height=2 hint- length= 2 width=3 and height=4 You must find the volume of 2 shapes and then add them
