Question

A cylindrical tank is of radius 7cm and height 3cm .find its
1. CSA 2.TSA 3.volume 4.capacity

Answer 1

Answer:

Step-by-step explanation:

Answer 2

There are some Formulas :-

$1). \: c.s.a = 2 \pi \: r \: h$

$= > c.s.a = 2 \times \frac{22}{7} \times 7 \times 3$

$= > c.s.a = 132 \: {cm}^{2}$

Again,

$2). \: t.s.a \: = 2 \pi \: r(r + h)$

$= > t.s.a = 2 \times \frac{22}{7} \times 7(7 + 3)$

$= > t.s.a = (308 + 132) \: {cm}^{2}$

$= > t.s.a = 440 \: {cm}^{2}$

Again,

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

$= > \: v \: \: = \frac{22}{7} \times 7 \times 7 \times 3$

$= > \: v \: \: = 462 \: {cm}^{3}$

As we know that Volume is equal to Capacity.

Therefore,

Capacity = 462 cm^3
