An ice cream container is made of a cylinder with a concave out hemisphere on top and a concave in hemisphere at the base. If the height of the cylinder is 20 cm and the diameter of the container is 14 cm, find the surface area and volume of the container.

What am I learning today?

How to write algebraic proofs for quadrilaterals

How will I show that I learned it?

Identify the most accurate name for a quadrilateral and prove it algebraically by its 

properties

Isosceles TrapezoidQuadrilateral with only one pair of opposite sides parallel, and non‐parallel sides are congruent

Oct 23­9:05 PM

Given the coordinates of four points, it is possible to determine which quadrilateral is being graphed: 

Parallelogram1 ‐ slopes of both pairs of opposite sides are equal2 ‐ lengths of both pairs of opposite sides are equal3 ‐ diagonals intersect at each of their midpoints

Rectangle1 ‐ slopes of both pairs of opposite sides are equal2 ‐ slopes of consecutive sides are opposite reciprocals3 ‐ diagonals intersect at each of their midpoints4 ‐ diagonals are the same length

Kite1 ‐ slopes of both pairs of opposite sides are  NOT   equal

2 ‐ two pairs of consecutive sides have same length(but not all four the same)

3 ‐ slopes of diagonals are opposite reciprocals

Isosceles Trapezoid1 ‐ slopes of only one pairs of opposite sides are   equal

2 ‐ other two sides are same length3 ‐ diagonals are the same length

Nov 14­10:23 AM

To prove a quadrilateral, you will use the following formulas:

Slope ­ parallel and perpendicular segments

Distance ­ lengths of segments

Midpoint ­ bisected segments
