Question

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

Answer 1

Answer:

$5.76975\times 10^{-8} km$

Step-by-step explanation:

1 m = 0.001 km

Diameter of conical pit = 3.5m

Radius = 3.5/2 =1.75 m= 0.00175 km

Depth of pit = 12m=0.012 km

Volume of conical pit = $\frac{1}{2} \pi r^{2} h$

                                    = $\frac{1}{2} \times 3.14\times 0.00175^{2} \times 0.012$

                                    = $5.76975\times 10^{-8}$

Hence the capacity of cone is $5.76975\times 10^{-8} km$
