The area of circle's sector is A= (1/2) x Txr²
where Teta = <span>42 degrees = 42/180Pi= 7Pi /30
r= 30/2= 15ft, r²= 125
so the areo of the slice of pie that was cut is A= (</span>7Pi <span>/60 ) x 125= 45.79 ft²</span>
Answer:
blue
Step-by-step explanation:
12*5*2=. 5*8=. 8*13=. 8*12=. Now times add all these up
<u><em>Answer:</em></u>
The bird is approximately 9 ft high up in the tree
<u><em>Explanation:</em></u>
The required diagram is shown in the attached image
Note that the tree, the cat and the ground form a right-angled triangle
<u>Therefore, we can apply special trigonometric functions</u>
<u>These functions are as follows:</u>
<u>Now, taking a look at our diagram, we can note the following:</u>
α = 25°
The opposite side is the required height (x)
The adjacent side is the distance between the cat and the tree = 20 ft
Therefore, we can use the <u>tan function</u>
<u>This is done as follows:</u>
which is 9 ft approximated to the nearest ft
Hope this helps :)
