Answer:
it is 40pi
Step-by-step explanation:
pi r^2 and you have 144 degrees shaded which is 40% of the circle.
You find the total volume to be 100pi and you divide by .4 (40%) to get 40pi as your answer
Answer:
I think its the third one but im not entirely sure
Step-by-step explanation:
Answer:
11.6
Step-by-step explanation:
There are 2 traingles one from the person to bottom of mirror and one from the bottom of the mirror to the top of the building
these are conjugate triangles so if the 3m represents 17.5
what does the 2 m represent?
2*17.5/3=35/3=11 2/3 so 11.6
Answer:
56
Step-by-step explanation:
The thing to realize is that the total of both angles that have x in them is that they add to 145. That's given.
<LKM + <MKN = 145
2x + 10 + 4x - 3 = 145 Combine like terms
6x + 7 = 145 Subtract 7 from both sides
6x = 138 Divide by 6
x = 138/6
x = 23
That's not the answer.
2x + 10 = <LKM
2*23 + 10 = <LKM
46 + 10 = <LKM
56 = <LKM
