Question

A circular well with a diameter of 2 meters, has a volume 44 m square what will the depth of the circular well?​

Answer 1

Answer- The above question is from the chapter 'Surface Areas and Volumes'.

Concept used: Volume of a cylinder = π r² h

For a circular well which is in the shape of cylinder,

Given: Diameter (d)= 2 m

Radius (r) = d/2 = 2/2 = 1 m

Volume = 44 m³

To find: Depth of circular well (h) = ?

Solution: Volume of cylinder = π r² h

44 = 22/7 × 1² × h

(44 × 7) ÷ 22 = h

2 × 7 = h

h = 14 m

Therefore, depth of circular well = 14 metres

Answer 2

Answer:

⇒ Depth of circular well = 14 m

Step-by-step explanation:

Question:-

A circular well with a diameter of 2 meters,has a volume of 44 m³ .What will be the depth of circular well?

Solution:-

Given:-

◗ Diameter of well(d) = 2 m

◗ Volume of well = 44 m³

To find:-

◗ Depth of well(h) = ?

At first:-

⇒ Radius = Diameter/2

⇒ Radius = 2/1

⇒ Radius = 1 m

As a circular well is like a cylinder,so can use formula for cylinder here.

Formula used here:-

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

• Putting values:-

$\dashrightarrow\sf 44 = 3.14 \times 1^2 \times h \\\\\dashrightarrow\sf 44 = 3.14 \times h \\\\\dashrightarrow\sf h = \dfrac{44}{3.14} \\\\\dashrightarrow\large{\underline{\boxed{\sf\green{Depth \:of \: well(h) = 14 \: m }}}}$

$\therefore{\underline{\textsf{Depth \: of \: well(h) = {\textbf{14 \: m }}}}}$
