Answer»

━━━━━━━━━━━━━━━━━━━━

\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.

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)..

If 5∠A = 3∠B = ∠C, ∠A and ∠B are complementary angles, then the measure of ∠A, ∠B and ∠C are respectively VALUE OF A,B AND C 280°, 57°, 160°(a) 33.75°, 56.25°, 168.75°(B) 281°, 56°, 168°(C) 271.50°, 58.25°, 160.75°(D)

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°

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
