Question

A grain silo has a cylindrical shape. Its diameter is, 19 ft and its height is 42 ft . What is the volume of the silo?

Answer 1

Answer:

• Volume of grain silo is 11902.17 feet³

$~$

Step-by-step explanation:

• Diameter of silo = 19 ft
• Radius = 19/2
• Height= 42 ft

$~$

$\longrightarrow {\pmb{\sf \: \:Volume \: of \: cylinder = \pi {r}^{2} h}}$

$~$

$\longrightarrow\sf \: \:Volume = 3.14 \times \bigg({ \dfrac{19}{2} } \bigg)^{2} \times 42$

$~$

$\longrightarrow\sf \: \: Volume = 3.14 \times \dfrac{19}{2} \times \dfrac{19}{2} \times 42$

$~$

$\longrightarrow\sf \: \: Volume = 3.14 \times \dfrac{361}{4} \times {42}$

$~$

$\longrightarrow\sf \: \: Volume = 3.14 \times \dfrac{15162}{4}$

$~$

$\longrightarrow\sf \: \: Volume =3.14 \times 3790.5$

$~$

$\longrightarrow\sf \: \: Volume = 11902.17 \: {feet}^{3}$

$~$

$\therefore$ Volume of grain silo is 11902.17 feet³
