Question

a conical pit of top diameter 3.5 m is 12m deep . What is its capacity in liters...​

Answer 1

Answer:

Step-by-step explanation:

d=3.5

r=d/2=3.5/2

h=12m

v=πr²h/3

v = 22/7 *3.5/2 * 3.5/2*12/3

v = 77/2m³

1m³=1000l

77/2m³=?

77*1000/2

38500l

Answer 2

Step-by-step explanation:

• Given:-
• Diameter = 3.5 m
• Height = 12 m

volume of the conical pit = 1/3πr²h

= 1/3 × 22/7 × 3.5 × 12

= 22/2 × 4

= 22 × 2

= 44m³

we know that 1m³ = 1 × 10^-9 km³

therefore 44m³ = 4.4 × 10^-8 km³
