Question

milk powder comes in a cylindrical container whose base has a diameter of 14cm and height of 20 cm find its volume.
​

Answer 1

$\huge{\underline{\underline{\pink{\tt{EXplanation!!!!!!!!!:}}}}}$

$\sf{\bold{\green{\underline{\underline{Given :}}}}}$

ꔷ Diameter = 14 cm

$\implies{\tt{\pink{\: Radius \: =\: \frac{14}{2} = 7}}}$

ꔷ Height = 20 cm

$\sf{\bold{\red{\underline{\underline{To \: Find :}}}}}$

ꔷ Volume of the cylindrical container =?

$\sf{\bold{\orange{\underline{\underline{Solution :}}}}}$

Volume of the Cylinder = 2πrh

$\implies{\tt{\blue{ 2×\frac{22}{7}×7×20}}}$

$\implies{\tt{\blue{880cm^3}}}$

$\implies{\tt{\red{\: Therefore, volume = 880cm^3}}}$

Answer 2

Volume of cylinder  = $\bf 3080cm^3$

${\large{\underline{\underline{\textbf{Given :}}}}}$

$\text{diameter}=\text{14 cm}$

$\text{height}(h) = \text{20 cm}$

${\large{\underline{\underline{\textbf{To Find :}}}}}$

$\text{Volume of cylinder}$

${\large{\underline{\underline{\textbf{Formula Applied :}}}}}$

$\text{Volume of cylinder} = \pi r^{2} h$

$\setlength{\unitlength}{1mm}\begin{picture}(5,5)\thicklines\multiput(-0.5,-1)(26,0){2}{\line(0,1){40}}\multiput(12.5,-1)(0,3.2){13}{\line(0,1){1.6}}\multiput(12.5,-1)(0,40){2}{\multiput(0,0)(2,0){7}{\line(1,0){1}}}\multiput(0,0)(0,40){2}{\qbezier(1,0)(12,3)(24,0)\qbezier(1,0)(-2,-1)(1,-2)\qbezier(24,0)(27,-1)(24,-2)\qbezier(1,-2)(12,-5)(24,-2)}\multiput(18,2)(0,32){2}{\sf{7cm}}\put(9,17.5){\sf{20cm}}\end{picture}$

${\large{\underline{\underline{\textbf{Solution :}}}}}$

To find volume we need to know radius of cylinder.

$\text{radius} = \frac{\text{diameter}}{2} \implies \frac{14}{2}$

$\text{radius (r)} = 7cm$

$\text{Volume } = \pi r^{2} h \implies \frac{22}{7} \times 7 \times 7\times 20$

$\text{Volume}= 22 \times 7 \times 20$

$\text{Volume} = 140 \times 22$

$\text{Volume} = 3080\:cm^3$
