Answer:
What is the missing term in the series 9, 27, 31,155, 161, 1127?
First number = 9
Second number = 9*3 = 27
Third number = 27+4 = 31
Fourth number = 31*5 = 155
Fifth number = 155+6 = 161
Sixth number = 161*7 =1127
Seventh number =1127+8 = 1135
Eighth number = 1135*9 = 10215
Ninth number = 10215+10 = 10225
Tenth number = 10225*11 =112475

Answer:
426.9 Km²
Step-by-step explanation:
The shaded area is the area of the triangle subtract the area of the circle.
Area of triangle = 0.5 bh ( b is the base and h the perpendicular height )
Here b = 40 and h = 27, thus
Area = 0.5 × 40 × 27 = 20 × 27 = 540 Km²
Area of circle = πr² ← r is the radius
Here the diameter is 12, thus radius = 12 ÷ 2 = 6
Area = π × 6² = 36π ≈ 113.1 Km²
Shaded area = 540 - 113.1 = 426.9 Km²

Step-by-step explanation:
As with many multiple-choice questions, the appropriate choices can often be determined with a simple test. Here, you only need to look at the values of the constants. (Those are ringed in blue.)
