The formula to find the area of a sector is:
A = 
In this case:
Degree = 40
Radius = 8
^^^Plug these numbers into the formula given above
A = 
Solve
A =
π8²
A =
π64
A = 
A = 7.1111111π
When rounded:
7.1π is the area of the sector

Answer:
The correct option is 1.
Step-by-step explanation:
it is given that the probability of a randomly selected point on the grid below is in the blue area is 9/16.
In the given grid we have only two colors that are blue and white.
Let A be the event of a randomly selected point on the given grid is in the blue area.

If the randomly selected point on the given grid does not lie in the blue area, it means it lies on white area.
We will calculate P(A'), to find the probability that a randomly selected point is in the white on the grid.
We know that the sum of the probability is 1.


It is given that 

Therefore option 1 is correct.
373-13=360
360 divided by three equal to 120
So 120 children chose basketball
Answer:
C) 15
Step-by-step explanation:
This is following the 30-60-90 triangle ratio which goes x (leg) ,x sqrt 3 (leg), 2x (hypotenuse).
So multiply 7 1/2 by 2 to get 15
Answer:
The two figures are similar and hey are not solid.
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
<em>Leah claims that these figures are not similar. When she compared the heights, she wrote 2/7. Then she compared the bases and 21/6. Why is Leah having trouble? Explain completely</em>
(Please have a look at the attached photo)
My answer:
In the first ratio, she compared the small figure's height to the large figure's height that is: 2/7
In the second ratio, she compared the large figure's base to the small figure's base that is: 21/6
=> She is wrong in this step, the ratio must be 6/21
Hence she needs to compare bases and heights thorugh division because the ratio between heights and the ratio between bases must be equal
The scales are equal
=> Therefore, those rectangles are congruent.
