Answer:

Step-by-step explanation:

7). Since, game board is circular in shape,

   Area of the game board = πr²

   Here r = radius of the circle

   And Radius of a circle = [tex]\frac{1}{2}(\text{Diameter})[/tex]

   Therefore, radius of the circle = [tex]\frac{2.5}{2}[/tex] = 1.25 ft

   Area of the game board = π(1.25)²

                                            = 3.14(1.25)²

                                            = 4.91

                                            ≈ 5 ft²

    Option C is the answer.

8). Scale on he map is,

   1 cm = 9.8 miles

   Distance between Old faithful and West Thumb = 2.5 cm

   By using scale,

   2.5 cm = 2.5 × 9.8 miles

                = 24.5 miles

   Therefore, actual distance between Old faithful and West Thumb = 24.5 miles.

9). From the given picture angles b and c are Vertically opposite angles.

    Therefore, these angles are vertical angles.

    Option D is the answer.
