Warm up
Warm up!

Find the surface area of the backpack to the nearest inch:


The base is 12 in, but what is the height? (Hint: what is the radius of the circle?)

The back has the same area:


The left side has the same area: the radius of the circle?)


The back has the same area: the radius of the circle?)


Spheres

Spheres the radius of the circle?)

Geometry

Unit 6, Day 6

Ms. Reed


What is a sphere
What is a Sphere? the radius of the circle?)

  • Definition:

    A 3-dimensional circle.

  • Examples:


Formulas

Surface Area the radius of the circle?)

Volume

Formulas


Example 1
Example #1 the radius of the circle?)

  • Calculate the volume of:

15”

V = 4/3 pr3

V = 4/3()(15)3

V 14130in3


Example 2
Example #2 the radius of the circle?)

  • Calculate the volume of:

V = 4/3 pr3

V = 4/3()(3.9)3

V 248.349in3


Example 3
Example #3 the radius of the circle?)

  • Calculate the surface area of:

S = 4pr2

S =4()(6.1)2

S 467.3576 in2
