Question

A conical pit of top diameter 3.5 m is 12 m deep. What is the capacity in kilolitres?

Answer 1

Answer:

Therefore, the capacity of conical pit is 38.5 kilolitres.

Step-by-step explanation:

Given:

Shape is of Cone

Diameter = d = 3.5 m

∴ Radius = $\dfrac{3.5}{2}=1.75$

Deep = Height = h = 12 m

Pi=$\dfrac{22}{7}$

To Find:

Volume of Conical Pit( in kilolitres) = ?

Solution:

Volume of Cone is given by the formula,

$\textrm{Volume of Cone}=\dfrac{1}{3}\pi (radius)^{2} \times height$

Substituting the values we get

$\textrm{Volume of Cone}=\dfrac{1}{3}\times \dfrac{22}{7}\times (1.75)^{2} \times 12=38.5\ m^{3}$

Also,

$1\ m^{3}=1000\ Litres=1\ kilolitres\\\\\therefore 38.5\ m^{3}=38.5\ kilolitres$

Therefore, the capacity of conical pit is 38.5 kilolitres.
