Question

a conical tank is 3 m deep & its circular top has radius is 1.75m find capacity of tank in kilolitres

Answer 1

given:-h=3m
r=1.75m

the volume of cone =1/3pi×r×r×h
=1/3×22/7×1.75×1.75×3
=385/40×1000/1000
=9.62kl

Answer 2

Answer:

9.61625 kiloliters.

Step-by-step explanation:

Height of conical tank = 3m

Radius of conical tank = 1.75 m

Volume of cone = $\frac{1}{3}\pi r^{2} h$

So, volume of conical tank =  $\frac{1}{3}\times 3.14 \times (1.75)^{2} \times 3$

                                             = $\frac{1}{3}\times 3.14 \times 3.0625\times 3$

                                             = $9.61625 m^3$

Since 1 cubic m = 1 kiloliter

So, 9.61625 cubic m = 9.61625 kiloliters.

Hence capacity of tank in kiloliters is 9.61625 kiloliters.
