2867.5 is bigger
Even though they both show 5 numbers, the second one has only one decimal place versus 2 on the first
If you ignore the decimal, your left with
290 vs 2867
2867 is much bigger than 290 so this is the answer
The bird will have been flying for 2 hours at 12 miles per hour. Because he is going 12 miles per hour, he will have gone 24 miles total.
In this question, we have to use the intersecting chord theorem, and the formula which is

In the given circle, values of AP, CP and DP are 12m, 6m and 5m respectively .
Substituting the values in the formula, we will get

Dividing both sides by 5

Answer:

Step-by-step explanation:
The base of the pyramid we need to study is a hexagon.
Let's look at the attached image of an hexagon to understand how we are going to find the area of this figure.
Notice that an hexagon is the combination of 6 exactly equal equilateral triangles in our case of size "2x" (notice that the "radius" of the hexagon is given as "2x")
Therefore the area of the hexagon is going to be 6 times the area of one of those equilateral triangles.
We know the area of a triangle is the product of its base times its height, divided by 2: 
We notice that the triangle's height is exactly what is called the "apothem" of the hexagon (depicted in green in our figure) which measures
, so replacing this value in the formula above for the area of one of the triangles:

Then we multiply this area times 6 to get the total area of the hexagon (6 of these triangles):
Area of hexagon = 
which is the last option given in the list.
