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: 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.
