6.	A bicycle wheel, diameter 70 cm, is making25 revolutions in 10 sec. At what speed in km/h isthe bicycle travelling? {ans-19.8km/hr}
Answer» ANSWER: 19.8 km/hr Step-by-step EXPLANATION: Diameter=70 CM PERIMETER of a circle is πd 22/770=220 cm Distance covered in 25 revolutions is 22025 5500 cm in 10 sec Speed=Distance/Time taken Since the answer should be in km/hr, let us convert 5500 cm into metres 5500 cm=0.055 km and 10 sec =1/360 hrs 55/1000 / 1/360 55/1000360 5536/100 1980/100 19.8 km/hr

6.

A bicycle wheel, diameter 70 cm, is making25 revolutions in 10 sec. At what speed in km/h isthe bicycle travelling? {ans-19.8km/hr}

Answer»

ANSWER:

19.8 km/hr

Step-by-step EXPLANATION:

Diameter=70 CM

PERIMETER of a circle is πd

22/7*70=220 cm

Distance covered in 25 revolutions is 220*25

5500 cm in 10 sec

Speed=Distance/Time taken

Since the answer should be in km/hr,

let us convert 5500 cm into metres

5500 cm=0.055 km and 10 sec =1/360 hrs

55/1000 / 1/360

55/1000*360

55*36/100

1980/100

19.8 km/hr

Step-by-step explanation:

2x+3y=7 ........(1)

7x-y=13

=>y=7x-13 ..........(2)

PUTTING value of y in from (2) in (1), we get

2x+3(7x-13)=7

39.	How to find the area of a sector whose radius is 35 cm and perimeter is 147 cm.
Answer» Answer:1347.5 square units Step-by-step explanation: radius = 35 cm Perimeter of sector = 147 cm L + 2R = 147 L + 2 (35) = 147 L + 70 = 147 L = 77 cm Now we have the length of an arc and radius. So we have to use the second FORMULA to FIND the area of the given sector. Area of the sector = (1/2) x l r square units = (1/2) x 77 x 35 ==> 38.5 x 35 ==> 1347.5 square units

39.

How to find the area of a sector whose radius is 35 cm and perimeter is 147 cm.

Answer»

Answer:1347.5 square units

Step-by-step explanation:

radius = 35 cm

Perimeter of sector = 147 cm

L + 2R = 147

L + 2 (35) = 147

L + 70 = 147

L = 77 cm

Now we have the length of an arc and radius. So we have to use the second FORMULA to FIND the area of the given sector.

Area of the sector = (1/2) x l r square units

The length of a rectangle exceeds its breadth by 9cm. If the length and breadth are each increased by 3cm, the area of the new rectangle will be 84cm sq more than that of the given rectangle. Find the length and breadth of the original rectangle. (Check your solution).

Answer»

Answer:

b=8cm

l=17CM

Step-by-step explanation:

BREADTH: b

Length: b+9

Area: (b)(b+9)

= $b^{2}$ +9B

New Breadth: b+3

New Length : b+9+3 = b+12

New Area: (b+12)(b+3)=84 + $b^{2}$ +9b

$b^2$ +15b+36=84+ $b^{2}$ +9b

6b=48

b=8cm

l=8+9

=17cm
