━━━━━━━━━━━━━━━━━━━━

$\sf\underbrace{Given: }$

A cylindrical water tank of diameter 1.4 m and height 2.1 m is being fed by a pipe of diameter 3.5 CM through which water flows at the rate of 2 metre per second. In how much time the tank will be filled?

$\sf\underline\red{Solution:}$

We have,

Diameter of cylindrical tank = 1.4 m
Radius of tank = d/2 = 1.4/2 = 0.7m
Height of tank = 2.1 m

Diameter of pipe FLOWING water in tank = 3.5 cm

Radius of pipe = d/2 = 3.5/2 cm
Rate of FLOW of water = 2 m/s

Time taken to fill the tank = volume of tank / volume of pipe × rate of flow

ㅤㅤ $→$ $\sf{= πr\:‑\:2h\: / \:(πr\:‑\:2 \:×\: 2)}$

$\\$

ㅤㅤ $\\$ $→$ $\sf{=\: (π \:×\: 0.7\: ×\: 0.7 \:× \:2.1)}$ / $\sf{\:(π\: ×\: 3.5/2 × 3.5/2\: × \:2)}$

$\\$

ㅤㅤ $→$ $\sf{=\: 1.029\: / \:6.125}$

$\\$

ㅤㅤ $→$ $\sf{= \:0.168}$

$\\$

ㅤㅤ $→$ $\sf{= \:1680 \:seconds}$

$\\$

ㅤㅤ $→$ $\sf{= \:28 \:minutes.}$

$\\$

∴ Time taken to fill the tank is 28minutes.

_____________________________

$\sf\underbrace{To\: know\:More: }$

Some Formula of Cylinder

Curved surface AREA of cylinder = 2πrh.

→ Base Area of cylinder = πr²

→ Both Side base Area of cylinder = 2(πr²)

→ Total Surface Area of cylinder = curvedsurface Area + both side base Area = 2πrh + 2πr² = 2πr (h+r)..

Answer»

GIVEN : 5∠A = 3∠B = ∠C, ∠A and ∠B are complementary angles

To Find : MEASURE of ∠A, ∠B and ∠C

Solution:

5∠A = 3∠B = ∠C

∠A and ∠B are complementary angles,

complementary angles, which adds up to 90° ( Right angle )

∠A + ∠B = 90°

=> 3∠A + 3∠B = 270°

=> 3∠A + 5∠A = 270°

=> 8∠A = 270°

=> ∠A = 270°/8

=> ∠A = 135°/4

=> ∠A = 33.75°

∠A + ∠B = 90°

=> 33.75°+ ∠B = 90°

=> ∠B = 56.25°

∠C = 5∠A = 5 * 33.75°

=> ∠C = 168.75°

A = 33.75°, B = 56.25°, C = 168.75°

Solution We have from construction , BCDE is a rectangle , ∴ BC = DE and CD = BE Now , from figure ∆AED is right angled triangle since DE ⏊ AB, From Pythagorean triplet we GET , $\sf\implies AD^{2} = DE^{2} + AE^{2} \\\\ \sf\implies 10^{2} = BC^{2} + (AB - BE)^{2} \: \: \: \{ \because BC = DE \} \\\\ \sf\implies AD^{2}= BC^{2} + (AB - CD)^{2} \: \: \: \: \{\because CD = BE\} \\\\ \sf\implies BC^{2} = AD^{2} - (AB - CD)^{2} \\\\ \sf\implies BC^{2} = 10^{2} - (9-3)^{2} \\\\ \sf\implies BC^{2} = 10^{2} - 6^{2} \\\\ \sf\implies BC^{2} = 100 - 36 \\\\ \sf\implies BC^{2} = 64 \\\\ \sf\implies BC^{2} = 8^{2} \\\\ \sf\implies BC = 8$ THEREFORE , the length of the side BC is 8cm

Q.2. Find the length of the side BC of the giventrapezium ABCD.

Answer»

Answer

The LENGTH of the side BC is 8cm

Given

ABCD is a TRAPEZIUM where :

AB = 9cm
AD = 10cm
CD = 3cm

To Find

The side BC

Construction

DE ⏊ AB is DRAWN so that BCDE become a rectangle.

Solution

We have from construction ,

BCDE is a rectangle ,

∴ BC = DE and CD = BE

Now , from figure

∆AED is right angled triangle since DE ⏊ AB,

From Pythagorean triplet we GET ,

$\sf\implies AD^{2} = DE^{2} + AE^{2} \\\\ \sf\implies 10^{2} = BC^{2} + (AB - BE)^{2} \: \: \: \{ \because BC = DE \} \\\\ \sf\implies AD^{2}= BC^{2} + (AB - CD)^{2} \: \: \: \: \{\because CD = BE\} \\\\ \sf\implies BC^{2} = AD^{2} - (AB - CD)^{2} \\\\ \sf\implies BC^{2} = 10^{2} - (9-3)^{2} \\\\ \sf\implies BC^{2} = 10^{2} - 6^{2} \\\\ \sf\implies BC^{2} = 100 - 36 \\\\ \sf\implies BC^{2} = 64 \\\\ \sf\implies BC^{2} = 8^{2} \\\\ \sf\implies BC = 8$

THEREFORE , the length of the side BC is 8cm
