the radii of two wheels of a railway engine are 120 cm and 8 cm respectively if the larger wheel makes 7540 revolutions to travel a certain distance find the number of the revolution made by smaller wheel to cover the same distance used pie 3.14

Answer»

Distance travelled by larger wheel..

GIVEN

Larger radius = 120 cm

SMALLER radius = 8 cm

no. of REVOLUTIONS of larger wheel (n1) = 7540

let no. revolutions of smaller wheel (N2) = ?

$distance \: \: covered by \: \: larger \: \: wheel \: \\ = n _{1}(2\pi \: r _{1} )\\ = 7540 \times 2\times \pi \times <klux>120</klux> \\ = 1809600\pi \\ or \\ 5682144 \: \: cm$

According to question

Distance covered by larger wheel = distance covered by smaller wheel..

$n _{2} (2\pi \: r _{2}) \: = n _{1} (2\pi \: r _{1}) \\ n _{2} (2\pi \times 8) = 1809600\pi \\ \\ n _{2} = \frac{1809600\pi}{2\pi \: \times 8} \\ \\ = 113100$

Answer» Questions (i) A CIRCULAR pond of diameter 28 m is surrounded by a path 7 m wide. Find the area of the path. (II) Find the area of a 2 m wide circular path surrounding a circular plot of radius 20 m. ____________________________ Answers (i) Given The diameter of circular pond is 28 m The pond is surrounded by a path 7 m wide To Find The Area of the Path Solution Area of Path ⇒ Area of the Pond with Path - Area of the Pond Radius of Pond ⇒ $\dfrac{28}{2} + 7$ = 21 m Radius of Pond along with Path ⇒ 27 - 7 = 14 m Area of Path ⇒ π (R² - r²) ⇒ π {(21)² - (14)²} ⇒ $\dfrac{22}{7} \{ 441 - 196\}$ ⇒ $\dfrac{22}{7} \times 245$ ⇒ $\dfrac{22}{7\div 7} \times 245\div 7$ ⇒ $22 \times 35$ ⇒ 770 m² ∴ The area of the path is 770 m² ____________________________ (ii) Given The radius of the circular plot is 20 m The circular plot is surrounded with a 2 m wide circular path.

Answer»

Questions

(i) A CIRCULAR pond of diameter 28 m is surrounded by a path 7 m wide. Find the area of the path.

(II) Find the area of a 2 m wide circular path surrounding a circular plot of radius 20 m.

____________________________

Answers

(i)

Given

The diameter of circular pond is 28 m
The pond is surrounded by a path 7 m wide

To Find

The Area of the Path

Solution

Area of Path ⇒ Area of the Pond with Path - Area of the Pond

Radius of Pond ⇒ $\dfrac{28}{2} + 7$ = 21 m

Radius of Pond along with Path ⇒ 27 - 7 = 14 m

Area of Path ⇒ π (R² - r²)

⇒ π {(21)² - (14)²}

⇒ $\dfrac{22}{7} \{ 441 - 196\}$

⇒ $\dfrac{22}{7} \times 245$

⇒ $\dfrac{22}{7\div 7} \times 245\div 7$

⇒ $22 \times 35$

⇒ 770 m²

∴ The area of the path is 770 m²

____________________________

(ii)

Given

The radius of the circular plot is 20 m
The circular plot is surrounded with a 2 m wide circular path.

To Find

The Area of the Path

Solution

Area of Path ⇒ Area of the Plot with Path - Area of the Plot

Radius of Plot ⇒ 20 + 2 = 22 m

Radius of Plot along with Path ⇒ 22 - 2 = 20 m

Area of Path ⇒ π (R² - r²)

⇒ π {(22)² - (20)²}

⇒ $\dfrac{22}{7} \{ 484 - 400\}$

⇒ $\dfrac{22}{7} \times 84$

⇒ $\dfrac{22}{7\div 7 } \times 84\div 7$

⇒ $22\times 12$

⇒ 264 m²

∴ The area of the path is 264 m²

Solve the following equation using cross multiplication method1/2(y+1)+1/12+1/14(y-1/3)=y/2

Answer»

Answer:

This equation can't be solved using cross multiplication method because the method is using only for 3 variables. There is one variable.

Step-by-step explanation:

1/2(y+1)+1/12+1/14(y-1/3)=y/2

or, y+1 + 1/6 + 1/21(y-1) = y [ eliminating 1/2 from both side ]

or, 1 + 1/6 + y/21 - 1/21 = 0 [ as, y-y = 0 ]

or, 7/6 + y/21 - 1/21 = 0

or, y/21 = - 47/42

or, y = - 47/2

So, the answer is: y = - 47/2

1. Find the measure of the side of a regular hexagon whose perimeter is 96 Cm

Answer»

$\huge\bold{\mathtt{Question⇒}}$

Find the measure of the side of a regular HEXAGON whose perimeter is 96 cm.

$\huge\bold{\mathtt{Given⇒}}$

Perimeter = 96 cm

$\huge\bold{\mathtt{To\:find⇒}}$

The LENGTH of its SIDES.

$\huge\bold{\mathtt{Solution⇒}}$

Perimeter = 96 cm

We know that a hexagon has 6 sides.

As the hexagon is regular, its sides are of equal length.

So, length of its sides

= $(\frac{\tiny{Perimeter}}{\tiny{Number\:of\:sides}})$ cm

= $(\frac{96}{6})$ cm

= $<klux>16</klux>$ cm

$\huge\bold{\mathtt{Hence⇒}}$

Length of its sides = 16 cm

$\huge\bold{\mathtt{Therefore⇒}}$

The length of the sides of the hexagon is 16 cm.

$\huge\bold{\mathtt{Done}}$

$\large\bold{\mathtt{Hope\:this\:helps\:you.}}$

$\large\bold{\mathtt{Have\:a\:nice\:day.}}$
