IM Geo.6.6 Practice: Completing the Square
Suppose a classmate missed the lessons on completing the square to find the center and radius of a circle. Explain the process to them. If it helps, use a problem you’ve already done as an example.
Match each expression with the value needed in the box in order for the expression to be a perfect square trinomial.
Find the center and radius of the circle represented by the equation .
Select all the expressions that can be factored into a squared binomial.
An equation of a circle is given by . Apply the distributive property to the squared binomials and rearrange the equation so that one side is 0.
Graph the circle (x+1)²+(y-3)²=16.
Find the distance from the center of the circle to each point on the list.
What do these distances tell you about whether each point is inside, on, or outside the circle?
The triangle whose vertices are and is transformed by the rule . Is the image similar or congruent to the original figure?
A cube has side length 3 inches. A sphere has a radius of 3 inches.
Before doing any calculations, predict which solid has greater surface area to volume ratio.
Calculate the surface area, volume, and surface area to volume ratio for each solid.
