Question

A water tank is cylindrical in shape and the diameter of its base is 28m .if it is 7m deep how many kilolitres of water can it hold

Answer 1

4310.27
because its radius of base will be 28/2m and height will be 7m so apply formula pie (its value is 22/7 or just put 3.14159 ) , r square , h
3.14 x 14 x 14 x 7 = 4310.27

Answer 2

Answer:

4312

Step-by-step explanation:

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

h=7m

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

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

$= 22 \times 196$

$= \boxed{4312}ans$
