please explain me​

Answer 1

$\large{\underline{\underline{\pmb{\sf{Question:}}}}}$

If the radius of the base of a cyclinder is 7cm and it's height is 15cm , find the volume of the cylinder.

$\large{\underline{\underline{\pmb{\sf{Required\:Answer:}}}}}$

Volume of the cylinder is 2310cm³.

$\large{\underline{\underline{\pmb{\sf{Given:}}}}}$

• Radius of cylinder = 7cm
• Height of the cylinder = 15cm

$\large{\underline{\underline{\pmb{\sf{To\:Find:}}}}}$

• Volume of the cylinder.

$\large{\underline{\underline{\pmb{\sf{Explanation:}}}}}$

To find the volume of the cylinder, we use the formula:

⇒ V = πr²h

where,

• V = Volume
• π = 22/7
• r = Radius
• h = Height

Let us use this formula to find the volume of the required cylinder.

⇒ V = πr²h

⇒ V = 22/7×(7)²×15

⇒ V = 22×7×15

⇒ V = 2310cm³

Hence, Volume of the cylinder is 2310cm³.

$\large{\underline{\underline{\pmb{\sf{Know\:More:}}}}}$

⇒ Volume of Cylinder = πr²h

⇒ CSA of Cylinder = 2πrh

⇒ TSA of Cylinder = 2πr(h+r)

Answer 2

Question :-

• If the radius of base of a cylinder is 7cm and it's height is 15 cm ,What is it's volume ?

ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎

GIVEN :-

• Radius of cylinder = 7cm
• Height of cylinder = 15 cm

ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎

TO FIND :-

• Volume of cylinder

ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎

FORMULA TO BE USED :-

• Volume of cylinder = πr²h

where,

• r = radius = 7 cm
• h = height = 15 cm
• π = 22/7

ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎

SOLUTION :-

❖ Substituting the values in formula :-

➯ Volume = πr²h

➨ Volume = 22/7 × (7)² × 15

➨ Volume = 22/7 × 49 × 15

➨ Volume = 22 × 7 × 15

➨ Volume = 2310

ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎

∴ , Volume of cylinder = 2310 cm³.
