Answer: 2.39 feet
Step-by-step explanation:
Hi, to answer this question we have to apply the formula:
V=πr^2h
Where:
V: volume of a cylinder
r: radius
h:height
Replacing with the values given
30 =π2^2 h
Solving for h
30 / (π2^2) =h
30 / 3.14 (4) =h
30/12.56 =h
2.39 feet = h
So, the correct option is 2.39 feet.

Answer:
1.
x = 44*2
<h2>x = 88</h2>
2.
x = 62*2
<h2>x = 124</h2>
3.
x = 108/2
<h2>x = 54</h2>
4.
x = 160/2
<h2>x = 80</h2>
5.
12x = 60*2
12x = 120
x = 120/12
<h2>x = 10</h2>
6.
5x = 50/2
5x = 25
x = 25/5
<h2>x = 5</h2>
