Tell me more…• Describe the habitat of you bears.• What are important features for bear

habitat?• Are the requirements different for

different bear species? Bears of different gender?

• What risks do humans pose to bear habitat?

Habitat AreaHabitat Area How can you use

math to describe a bear’s habitat?

What other methods could you use?

Bear Habitat AreaBear Habitat Area

Some Geometry…• Area of a Circle: π x R2 • Circumference of a circle: π x 2 x R

How might we define the location of the center of the circle?
