Answer:
4712.4
Step-by-step explanation:
I got the same question a few days ago.
The volume is πr^2 * h / 3
r = 15
h = 20
225π * 20 / 3
1500π
It's 4712.38898
Round to 4712.4

Put it like that and there’s your constant
Answer:
EF = ~3.8
Step-by-step explanation:
Apply the sine theorem:
EF/sinD = DE/sinF
=> EF = DE*(sinD/sinF)
= 3*(sin75/sin50)
=3.78 = ~3.8
Hope this helps!
Y=mx+b is our base equation
m=slope, so let's find that first:
m= change in y/change in x
So between the points (-1,-2) and (3,4),
The y values, -2 and 4, have a difference of 6. The x values, -1 and 3, have a difference of 4. This makes our slope 6/4 (or 3/2 simplified)
Now our equation is
Y=3/2x + b
We still need to find b
To find b, we can substitute a point given to us. Let's use (3,4) just to avoid negatives.
4=3/2(3) + b
Multiply
4=9/2 + b
Subtract 9/2 from both sides
-1/2=b
Now let's put it all back together!
Y=3/2x-1/2 Is the answer.
I hope this Helps!
