non sense

Total distance = 225.632 + 14.132

= 239.764 km

answer is wrong

area = length× width44cm /15 = breadth2.9cm

Rectangle sheet length = 44cm, breadth = 18cm

By rolling along length of sheetCylinder length = 18 cmCylinder circumference = 44cm

r= radius of cylinder

2*pi*r = 442*22/7*r = 44r = 7 cm

Volume of cylinder = pi*r*r*h= (22/7)*7*7*18= 22*7*18= 2772 cm^3

Q.The length of equator of a globe is 44cm find its surface area?ans.Length of the equator of the globe or circumference of a globe = 44 cm r = ? Circumference = of the globe = 2πr 44 = 2*22/7*r r = (44*7)/44 r = 7 cm.

Length of the equator of the globe =44cm r circumference = of the globe =2¥®44=2*22/7*rr=[44*7]/44r=7cm

Length of the equator of the globe or circumference of a globe = 44 cm

r = ?

Circumference = of the globe = 2πr

44 = 2*22/7*rr = (44*7)/44r = 7 cm

Now,Surface area of the globe = 4πr²= 4*22/7*7*7

Surface area = 616 cm²

Motionmeans change of position with time. Abodyissaid to be in motionwhen it's position changes continuously with respect to a stationary object taken as reference point.

speed = distance *time

since the train length is 10 m , speed = 160*14.4 = 2304 m/s

=> speed= 17 km per hour

1 necklace has 3 strands12500 necklace has 12500×3 = 37,500 strands

1strand have 75 pearls37,500 strands will have 37500×75 = 28,12,500 pearls

1 packet contain 100 pearls Therefore,Number of packets of 100 pearls needed for 12,500 necklaces = 2812500÷100 = 28,125 packets

28,125 packets is the best answer

Profession is a paid occupation, especially one that involves prolonged training and a formal qualification.

option (3) will be right .

Dont know the answer

Sin is negative in 3rd and 4th quadrant

Sin π/6 = 1/2

Value in 3rd quadrant

π+π/6

= 7π/6 = 210°

Value in 4th quadrant

2π - π/6

= 11π/6 = 330°

So the values are 210° and 330°

(1) 4^3 * 2^3 = (4*2)^3 = 8^3

(3) (-2)^4 * (-3)^4 = (-2*-3)^4 = (6)^4

Length of the sheet = circumference of cylinder base2*pi*r=44cm2*22/7*r=44r=(44*7)/(2*22)r=7cmthereforecylinder radius=r=7cmheight of the cylinder=breadth of the rectangleh=18cmvolume of the cylinder =pi*r^2*h=22/7*7*7*18=22*7*18=2772cm^3

So the train covers (240+992/1000)km in total.d=240.992 t=8 So velocity= distance/time = 240.992/8=30.124Now, for t=1 hourdistance=velocity×time = 30.124×1 = 30.124 km.So In 1 hour it travels 30.124 km.
