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

2.39 feet is the answer

Answer 2

Answer: 2.39 feet

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.
