Answer:
h= 24
Step-by-step explanation:



r= 7
1230.88=3.14×7^2×h/3
1230.88= 153.86h/3
h=1230.88/153.86
h= 24
Answer:
On a number line, negative five and positive five are the same distance from zero.
Step-by-step explanation:
Since the equations for area is A= L*W
A= 9*4= 54
Answer:
<h2>
aₙ = 7n - 10</h2>
Step-by-step explanation:
The nth term: 
So:
a₄ = a₁ + 3d
18 = a₁ + 3d ⇒ 3d = 18 - a₁
a₇ = a₁ + 6d
39 = a₁ + 6d
39 = a₁ + 2(18 - a₁)
39 = a₁ + 36 - 2a₁
39 = 36 - a₁
a₁ = -3
3d = 18 - (-3)
3d = 21
d = 7
So the nth term:

Answer:
X=0
Step-by-step explanation:
4x=0
divide both sides by 4
x=0/4
x=0
