Answer:
D.76.44 square units
Step-by-step explanation:
We are given that
Base of one sector=b=1.95 units
Height of sector=h=4.9 units
Total number of sectors=16
Area of one sector is equal to area of triangle (approximately)
Area of sector=
Using the formula
Area of one sector= square units
Area of circle A=area of sector
Area of circle A= square units
Hence,option D is true.

Answer:
h = 2.5
Step by step explanation:
We have been given an equation that models the total miles Michael traveled one afternoon while sledding, where u equals the number of hours walking up a hill and (u – 2) equals the number of hours sledding down the hill.
To find value of u we will solve our equation.
Upon using distributive property we will get,
Now let us add 18 to both sides of our equation.
Now let us combine like terms.
Upon dividing both sides of our equation by 10.5 we will get,
Therefore, value of u is 2.5.
Answer: Last option.
Step-by-step explanation:
Observe the base of the pyramid, which is a regular hexagon. You can see that there is a right triangle.
The area of the triangle can be calculated with this formula:
Where "b" is the base and "h" is the height.
You can say that the apothem is the height of the right triangle, then, you need to find the base applying the Pythagorean Theorem:
Then, the area of the triangle is:
Since the base of the pyramid is a regular hexagon, then you can multiply by 12 the area of the right triangle calculated above, in order to find the area of the hexagon. Then you get:
