Question

The capacity of a cylindrical water tank is 17600l and its depth is 1.8 m find it base radius

Answer 1

Answer:Volume of cylinder =pie r^2 h

volume=17600l

=17600/1000 m^3 (1m^3=1000l)

=17.6 m^3

On putting this on above formula,

17.6=22/7×r^2×1.8

r^2=7×4/9

r^2=28/9

r=root28/9

=2root7/3

Hence r= 2root7/3

Step-by-step explanation:

Answer 2

The base radius is 1.763 m

Step-by-step explanation:

Depth of cylinder = 1.8 m

1 cubic m = 1000 liters

The capacity of a cylindrical water tank is 17600 l

1000 liters = 1 cubic m

$1 = \frac{1}{1000} cubic m$

$17600 l = \frac{1}{1000} \times 17600$

$17600 l =17.6 cubic m$

Volume of cylinder =$\pi r^2 h = \frac{22}{7} \times r^2 \times 1.8$

We are given that The capacity of a cylindrical water tank is 17.6 cubic m

So,  $\frac{22}{7} \times r^2 \times 1.8 = 17.6$

$r=\sqrt{\frac{17.6 \times 7}{22 \times 1.8}}$

r=1.763

Hence The base radius is 1.763 m
