Answer:
D
Step-by-step explanation:
Okay so the ∠2 = 40deg. That means ∠2 + ∠6 = 180
∠6 = 180 - 140
Same goes for ∠1, ∠1 + ∠2 = 180, ∠1 = 180 - 40 = 140
∠1 + ∠6 = 140 + 140 = 280degrees = Ans D
This question is asking for the volume of the cone.
The formula is 1/3π r²h where r is radius and h is height.
First we must find the radius by dividing the diameter in half, giving us 3.5
Now we plug our values into the formula like this:
1/3 π r²h
1/3 π3.5² 13
This gives us the answer of 166.76mL or 166.8mL depending on how you want to round it.
Hope this helps :)
He was thinking of 23
I’ve attached my work on how I got it....
You do the opposite sign of what is given

So 2/3 of 36 is 24. So 24 that were filled and 2/3 of 40 is 80/3 which equals 26 2/3 to drain it. And then to fill the pool would be 36 hours. What's so hard...
