Answer 1

Question:

Find the total surface area of an open tank of radius 6.3 m and height 3.5 m. How many litres of water can it hold?

Answer:

$The \: tank \: will \: hold \:\bold{38808\:litres}$

To find:

To find the T.S.A of the tank in litres.

Given data:

Radius of the tank ( r ) = 6.3 m

Height of the tank ( h ) = 3.5 m

Step-by-step explanation:

We know that tank shape is cylinder.

$\boxed{T.S.A \: of \: cylinder = 2 \pi r(r + h)}$

$The \: value \: of \: \pi = \frac{22}{7}$

$= 2 \times \frac{22}{7} \times 6.3 \times (6.3 + 3.5)$

$= \frac{2 \times 22 \times 6.3 \times 9.8}{7}$

$= \frac{2716.56}{7}$

$\implies 388.08 {m}^{2}$

We know that 1 liter = 0.01 m²

388.08 m² = 38808 litres

$\implies \boxed{38808l}$

∴ The tank will hold 38808 litres .
