Answer:

$889.67\ m^(3)$

Explanation:

we know that

The volume of the composite solid is equal to the volume of the cylinder plus the volume of a cone

The volume of the cylinder is equal to

$V=\pi r^(2)h$

we have

$r=5\ m$

$h=10\ m$

substitute

$V=\pi (5)^(2)(10)=250\pi\ m^(3)$

The volume of the cone is equal to

$V=(1/3)\pi r^(2)h$

we have

$r=5\ m$

$h=4\ m$

substitute

$V=(1/3)\pi (5)^(2)(4)=(100/3) \pi\ m^(3)$

The volume of the composite solid is

$250\pi\ m^(3)+(100/3) \pi\ m^(3)=(850/3) \pi\ m^(3)$

assume

$\pi=3.14$

$(850/3)(3.14)=889.67\ m^(3)$
