Question

a water tank is cylindrical in shape and the diameter of its base is 28 m if it is 7m Deep How many kiloliters of water can it hold

Answer 1

Given ,

Radius of its base is 14 m.

Height of the cylinder is 7 m.

We know that ,

VOLUME OF THE CYLINDRICAL TANK = π*r^2*h = 22/7*14*14*7 = 4.312 kl.

Answer 2

r=14m (diameter/2=28/2=14)

h=7m

$\large \bold{v} = \large \blue{\pi {r}^{2} h}$

$= \frac{22}{ \cancel7} \times 14 \times 14 \times \cancel7$

$= 22 \times 196$

$= \boxed{4312}ans$
