Question

A conical pit of top diameter 3.5 m is 12m deep . what is its capacity in kilolitres?​

Answer 1

Answer:

radius of pit = r= 3.5/2 = 1.75 m

height of pit = depth of pit = 12m

so, volume of pit = 1/3 λr²h

= 1/3 x 22/7 x 1.75² x 12

= 38.5 m³

capacity of pit = 38.5 x 1 = 38.5 kl

Answer 2

Step-by-step explanation:

Heya!!

Given :-

• A conical pit of top diameter 3.5 m is 12m deep

To Find :-

• what is its capacity in kilolitres?

Solution :-

Radius = 3.5 / 2 m

           = 1.75 m

Height = 12 m

Volume of pit    = 1/3 πr²h

    = 1/3 × 22/7 × ( 1.75)² × 12cm³

            = 38.5 m³

Hence capacity of the pit = ( 38.5 ×1 ) kiloliters = 38.5 kiloliters.
