Question

if a well of diameter 8m has been dug to the depth of 14m then the volume of earth dug out is?? plzz answer urgently ​

Answer 1

Answer:

The volume of the earth dug is 704 m³.

Step-by-step explanation:

Given :

Diameter = 8 m

Depth = 14 m

To find :

The Volume of earth dug out

Solution :

Well is a cylinder, the volume is cylinder will be the volume of the earth dug out. The depth is the height.

★ Volume = πr²h

• Height = 14 m
• Radius = 8/2 = 4 m

⇒ 22/7 × 4 × 4 × 14

⇒ 22/7 × 16 × 14

⇒ 22/7 × 224

⇒ 4928/7

⇒ 704

Volume = 704 m³

Therefore, the volume of the earth dug is 704 m³.

Answer 2

★${\underline{\underline{\large{\mathtt{QUESTION:-}}}}}$

If a well of diameter 8 m has been dug to the depth of 14 m , then the volume of earth dug out is ?

★${\underline{\underline{\large{\mathtt{EXPLANATION:-}}}}}$

•Given:-

• Diameter = 8 m.
• Depth = 14 m.

•To find:-

• The volume of earth dug out.

•Solution:-

The well is a cylinder.

Radius = 8/2 = 4 m.

Height = Depth = 14 m.

We know,

${\boxed{\sf{\green{Volume\:of\: cylinder=\pi\:r^2\:h}}}}$

Volume = πr²h

→Volume = $\sf{\frac{22}{7}\times\:4\times\:4\times\:14\:cm^3}$

→Volume = 22×4×4×2 cm³

→ Volume = 704 cm³

★${\underline{\underline{\large{\mathtt{ANSWER:-}}}}}$

Hence the volume of the earth dug out is 704 cm³.
