A cylinder shaped bucket is used as a sand container. The bucket has a height of 2. 5 ft and a radius of 0. 5 ft. How many cubic

meriva

1.96 feet³

$\quad\rule{300pt}{1pt}\quad$

<h3>Ⲋⲟⳑⳙⲧⳕⲟⲛ :</h3>

We are given that a cylinder shaped bucket is used as a sand container . We have to find how much sand it can hold , which can be found by knowing the volume of cylindrical bucket .The volume of a cylinder is given by :

$\quad\dashrightarrow\quad {\pmb{\sf {Volume = \pi r^2 h }}}$

where,

π = 3.14
r = 0.5 feet
h = 2.5 feet

$\quad\dashrightarrow\quad \sf {V =\pi r^2 h }$

$\quad\dashrightarrow\quad \sf { V = 3.14 \times 0.5^2 \times 2.5}$

$\quad\dashrightarrow\quad \sf {V = 3.14\times 0.5\times 0.5\times 2.5 }$

$\quad\dashrightarrow\quad \sf {V = 1.9625 }$

‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ~Hence, the bucket can hold 1.96 feet³ of sand!

$\rule{350pt}{2pt}$
