Question

the diameter of a closed cylindrical water storage tank is 14 and its height is 20 m find the capacity of the tank

Answer 1

hope this helps you

Answer 2

Answer:

= 3080m³

Step-by-step explanation:

Given

• Diameter =14 m(given)
• Height = 20m (given)
• Radius =
• $\frac{d}{2} = \frac{14}{2} = 7$

To find

• Total surface area

Solution

We know that,

Total surface area

$2\pi \: r(r + h)$

$= 2 \times \frac{22}{7} \times 7(7 + 20)$

$= 44 \times 27 \\ = 1188 {m}^{3}$

$volume = \pi {r}^{2} h$

$= \frac{22}{2} \times 7 \times 7 \times 20$

$= 22 \times 7 \times 20$

$= 3080 {m}^{3}$
