Question

A plastic cylinder with the circular base of diameter 7cm and height 10cm. which container has greater capacity and by how much?​

Answer 1

Correct Question

A plastic cylinder with the circular base of diameter 7cm and height 10cm.And a plastic tube in which r =14 height 5cm which container has greater capacity and by how much

✪AnSwEr

${\tt{\red{\underline{\large{Given}}}}}$

• Cylindrical plastic
• r = 7/2 Height = 10cm

• Plastic tube
• r=5 and h = 8cm

${\sf{\green{\underline{\large{To\:find}}}}}$

• Which container has greater capacity

• And by how much

${\sf{\pink{\underline{\Large{Explanation}}}}}$

We know that

Volume of cylinder = πr²h

For cylindrical container

• Volume = πr²h

putting values

$= \frac{22}{7} \times 7 \times 5 \\ = 110$

110cm³

For cylindrical tube

• Volume = πr²h

putting values

$= \frac{22}{7} \times14 \times 5$

=220cm³

Here volume of cylindrical tube

Comparing

=(220-110)cm³

=110cm³

A plastic cylinder with the circular base of diameter 7cm and height 10cm. which container has greater capacity and by how much?

${ \huge{ \bold{ \underline{ \underline{ \red{Answer:-}}}}}}$

✒Given : -

• Radius(r) = 7/2
• Height(h) = 10cm

✒To Find : -

• Volume = ?

✒Formula Used : -

$\leadsto\sf{{ \small{ \bold{ \bold{ \bold{ \green{Volume\:of\:Cylinder=\pi{{r}^{2}h}}}}}}}}$

✒On Substituting Values : -

$\dashrightarrow\sf{\dfrac{22}{{\cancel{7}}}\times{{\cancel{7}}}\times{5}}$

$\dashrightarrow\sf{22\times{5}}$

$\dashrightarrow\sf{110{cm}^{3}}$

⤳For Cylindrical Tube : -

✒Formula Used : -

$\leadsto\sf{{ \small{ \bold{ \bold{ \bold{ \green{Volume\:of\:Cylinder=\pi{{r}^{2}h}}}}}}}}$

✒On Substituting Values : -

$\dashrightarrow\sf{\dfrac{22}{{\cancel{7}}}\times{{\cancel{14}}}\times{5}}$

$\dashrightarrow\sf{22\times{2}\times{5}}$

$\dashrightarrow\sf{220{cm}^{3}}$

✒Now ,

✒On Comparing : -

$\dashrightarrow\sf{(220-110){cm}^{3}}$

$\dashrightarrow\sf\bold{110{cm}^{3}}$
