Question

a conical pit of top diameter 3.5 m is 12m deep. what is it capacity in kilolitres​

Answer 1

hey mate

here is your answer

Answer:

38.5 kl

Step-by-step explanation:

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

ANsWeR :-

Radius = 3.5/2 = 1.75

Volume of Cone = 1/3 πr^2h

=> 1/3 × 22/7 × 1.75 ×1.75 × 12

=> 22/7 × 3.0625 × 4

=> 38.5 m^3

Converting in kilolitres :-

=> 38.5 kl
