Question

A cylindrical rain barrel has a radius of 2 feet and holds a total of 30 cubic feet of water. How tall is the rain barrel? Use 3.14 for pi. Round your answer to the nearest hundredth. (4 points) 1.58 feet 2.39 feet 3.57 feet 4.78 feet

Answer 1

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.

Feel free to ask for more if needed or if you did not understand something.

Answer 2

2.39 feet is the answer
