4. Assessment Focus Use 0.5-cm grid paper. Draw a circle with radius 5 cm.
Draw a square outside the circle that just encloses the circle.
Draw a square inside the circle so that its vertices lie on the circle.
a) How can you use the areas of the two squares to estimate
the area of the circle?
b) Check your estimate in part a by calculating the area
of the circle.
c) Repeat the activity for circles with different radii.
Record your results.

Which mathematical statements are true? 1) if 3 is an odd number, then 3 times 3 is an even number. 2) if 6 is less than 7, then 4 is greater than 7. 3) six is divisible by 3, and 10 is a multiple of 2. 4) the average of the data is greater than the largest value in the data, or it’s less than the largest value in the data. 5) the slope of a linear graph is its rate of change, and the graph’s y-intercept is the initial value. 6) if an equilateral triangle has equal angles, then all its angles will measure 45°.
