This is a graded discussion: 100 points possible due Apr 10 Discussion - Lesson 20 105 105 1. Compare and contrast pyramids and cones. Be sure to use mathematical terms to describe parts of the solids. a. In what ways are they alike? b. In what ways are they different? 2. Choose either pyramids or cones, and explain how the formula for their volume can be described using other solids. Please number your responses to the questions as they are shown (1a, 1b, and 2). Rubric: The Discussion Board Rubric is here to guide your responses. It will be used to evaluate your post.

It is 21 times the volume of an Apple iphone 4. If your brain were a cube, the edge length of a side would be 4.3 inches, or about one-third of a foot. If your brain were a sphere with a radius of 2.7 inches, what would be its volume? O 79 in^3 O 21 in^3 O 12.9 in^3 O 4.2 in^3Question 2 25 pts Early civilizations used standard measuring pottery to measure volume. As recently at the 1800's in the U.S. units of measures varied from area to area. When California became a state in 1850, one of the first laws passed was to establish weights and measures standards. What is the volume of the cylinder? 10 in 4 in O 400 in^3 O 40 in^3 O 20 in^3 O 502.65 in^3D Question 3 25 pts Pyramids of ancient Egypt were built of bricks weighing between 2 and 50 tons each. Twenty years and 10,000 men were required to build the largest pyramids. Overall, 100,000 skilled workers built these pyramids. Pyramid building was not done by slaves, as once thought. Paid workers built the pyramid with exact measurements of unknown origin who were proud of their work. h=9 cm 8 cm 8 cm O 576 cm^3 O 190 cm^3 O 192 cm^3 O 144 cm^3Question 4 25 pts Pine cones are not truly cones, but they have an interesting history. Here are a few: The pine cone is the official Maine State Flower, and it is the only state to have a state flower that is not a flower. Pine cones were a dinosaur delicacy. We have pine cones in our brains, sort of. The pineal gland is named for its cone shape. The pineal governs our perception of light and our wake/sleep patterns. What is the volume of this cone? -17.7 mm -12.4 mm O 2721 mm^3 O 103.83 mm^3 2850 mm^3 O 48.78 mm^3
