Question

capacity of a water tank is 924m² and radius of its base is 7m. find its height​

Answer 1

Given:-

capacity of a water tank = 924m³

radius = 7m

h = ?

We know that:-

Volume of a cylinder = pi r²h

924 = 22 × 7² × h

7

924 = 22 × 7 × 7 × h

7

924 = 22 × 7 × h

h = 924

22 × 7

h = 6 m

Therefore, the required height of the tank is 6 m.

Answer 2

Its height is 6 m

Step-by-step explanation:

Let the height of cylindrical tank be h

Radius of tank = 7 m

Volume of tank =

$\pi r^2 hπr$

So, Volume of given tank =

$\frac{22}{7} \times 7^2 \times h$

We are given that Capacity of a cylindrical tank is 924

$So,\frac{22}{7} \times 7^2 \times h = 924$

$h=924 \times \frac{7}{22 \times 7^2}$

h= 6

Hence its height is 6 m
