I should think that this works just like the trapezoids
volume=base times height
so
base=pir^2
height=x
r=d/2=14/2=7
base=pi7^2=49pi
so
V=49pix
1176pi=49pix
divide both sides by 49pi
24=x
I would say 24 units
Answer:
10
Step-by-step explanation:
3 is 15% of what number...
3 = 0.15x
3 / 0.15 = x
20 = x <=== 3 is 15% of 20
Answer:
Step-by-step explanation:
Hi there,
To solve this problem, we will need to isolate the variable by moving the variable to one side and the number to the other side.
1. - 16.5v - 19.94 = 19.39 - 9.6v <em>Rewrite the problem</em>
2. - 16.5v = 39.33 - 9.6v <em>Move the non-variable number to one side</em>
3. -6.9v = 39.33 <em>Isolate the variable</em>
4. v = - 5.7 <em>Divide by -6.9</em>
Thus, we can see the answer to this problem is v = - 5.7.
Have a good day,

The line through (a,b) and (c,d) is
(c-a)(y-b) = (d-b)(x-a)
Picking the last two points,
(-2 - -6)(y - -21) = (-14 - -21)(x - -6)
4(y+21) = 7(x+6)
When x=0
4y + 84 = 42
4y = -42
y = -21/2
Answer: -21/2
We never used the first point, let's check it's on the line
4(y+21) = 7(x+2)
4(-28 + 21) = -28
7(-10 + 6) = -28, good
