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
enot [183]

Answer:

2.39 feet

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

V=\pi r^{2}h

where

r is the radius of the base of the cylinder

h is the height of the cylinder

we have

V=30\ ft^3

r=2\ ft

\pi =3.14

substitute

30=(3.14)(2^{2})h

Solve for h

30=(3.14)(4)h

h=30/12.56

h=2.39\ ft
