You are designing a container in the shape of a cylinder. The radius is 5 inches. You want the container to hold at least 725π c
12345 [234]

Answer:

The answer to your question is: h = 14.5 in

Step-by-step explanation:

Data

radius = 5 in

Volume = 725 π in³

height = ?

Formula

               Volume = 2πr²h

           

Substitution

                     725 π in³ = 2πr² h

                    h = 725π / 2πr²

                    h = 725 / 2(5)²

                    h = 725 / 50

                    h = 14.5 in
