Question

Grain silo cylindrical Diameter 15 ft Height 31 ftwhat is thrme volume?use the value 3.14 for pie round to the nearest whole number

Answer 1

Answer:

5475 cubic ft

Explanation:

The volume of a cylinder is given by

$V=\pi r^2h$

where

r = radius of the base

h = height of the cylinder.

Now in our case,

r = 15 / 2 = 7.5 ft

h = 31ft

therefore, the volume is

$V=\pi(7.5)^2\cdot31$

using π = 3.14 gives

$V=(3.14)(7.5)^2\cdot31$

The right-hand side of the above equation simplifies to give

$V=5475.375$

rounding to the nearest whole number gives

$\boxed{V=5475.}$

Hence, the volume of the grain silo is 5475 cubic ft.
