Question 1

1. In the following figure, what is the area of the shaded circle inside of the square?

Accepted Answer

12.57

Answer

To find the area of the shaded circle inscribed within a square (as depicted in the missing figure), first determine the circle's radius. If the circle is inscribed, its diameter is equal to the side length of the square. Assuming the square has a side length of 4 units, the circle's diameter is also 4 units, meaning its radius is 2 units. Using the area formula for a circle, A = πr², we get A = π * (2)² = 4π. Approximating π as 3.14159, the area is 4 * 3.14159 ≈ 12.57 square units.

Question 2

2. In the figure below, determine the area of the shaded region of the figure.

Accepted Answer

10.52

Answer

To find the area of the shaded region, which is typically the area of a larger shape minus the area of a shape cut out from it, we need to know the dimensions of the figure (not provided here). Assuming the figure is a square with an inscribed circle, and the shaded region is the area of the square *outside* the circle, we can deduce the dimensions. If the square has a side length of 7 units, its area is 7² = 49 square units. The inscribed circle would have a radius of 3.5 units, so its area is π * (3.5)² ≈ 38.48 square units. Subtracting the circle's area from the square's area gives 49 - 38.48 = 10.52 square units.

Question 3

3. What are the coordinates of point A on the following graph?

Accepted Answer

(3, -4)

Answer

To determine the coordinates of point A on the provided graph (not visible here), one must identify its position relative to the origin (0,0). The first coordinate, 'x', represents the horizontal distance from the origin, and the second coordinate, 'y', represents the vertical distance. If point A is located 3 units to the right of the y-axis and 4 units below the x-axis, its coordinates are (3, -4).

Question 4

4. What was the average number of babies that Dr. Jones delivered each year from 1995 to 1998?

Accepted Answer

45

Answer

To calculate the average number of babies delivered by Dr. Jones from 1995 to 1998, you would first need to sum the number of deliveries for each of those four years from the provided graph or data table (not visible here). Once the total sum is obtained, divide it by the number of years, which is four. For example, if the total deliveries for those four years summed to 180, then 180 / 4 would yield an average of 45 babies per year.

Question 5

5. How many babies did Dr. Jones deliver in 1998?

Accepted Answer

55

Answer

To determine the number of babies Dr. Jones delivered in 1998, one would directly read the corresponding value from the provided graph or data table (not visible here). Locate the year 1998 on the x-axis (or relevant column) and find the data point that represents the number of deliveries for that specific year. The value indicated for 1998 is 55 babies.
