A wheel has radius 42 cm.(a) Find the distance covered in 700 revolutions(b) In how many revolutions will it cover a distance of 3 km 960 m? |
|
Answer» Circumference will be the distance covered in one revolutionHence2πr=2*22/7*42=264cm^2a)Hence in 700 revolutions=700*264=184800cm^2Now 3km 960m=3000m+960m=3960mHence,Revolutions will be 3960/264=15revolutions |

souravranjanrout 14 days agoHow many numbers less than 4500 when divided by 56 & 72 will leave a remainder of 39 In each case |
|
Answer» L.C.M of 56&72 is 504. So there are numbers multiple of 504 plus 39 but less than 4500. Now 504×9=4536 which is >4500. So there are 8 numbers which will satify the condition. Thus following are the numbers: 504+39=543,504×2+39=1047, 504×3+39=1551, 504×4+39=2055, 504×5+39=2559,504×6+39=3063, 504x7+39=3567 & 504×8+39=4071. Ans: 8 numbers. |

Vhich of the following statements is/are True' or False'?(i) The sum of two angles which form a linear pair is always equal to 180°(ü) The complement of 90° is 90°The supplement of an acute angle is always an obtuse angle.(iv) The supplement of a right angle is also a right angle.(v) The sum of two adjacent angles is supplementary.(üi) |
|
Answer» 5 is also True?? yes...The adjacent angles will have the common side and the commonvertex. Two angles are said to be supplementary angles if the sum of both the angles is 180 degrees. If the two supplementary angles are adjacent to each other then they are called linear pair. Sum of two adjacent supplementary angles = 180 okk..Thanks for telling..Now I got it! truefalse truetruetrue |

InIn AABC, AB 26 cm, BC 28 cm and the altitude AD 24 cm. Calculate AAABC, AB 26 cm, BC 28 cm and the altitude AD24 cm. Calculate AC. |
|
Answer» it is given that in a triangle ABC, AB=26 cm, BC=28 cm, altitude(height)=24 cm then AC value can be calculated by, let AD the altitude be a median which divides BC into half so, BC=DC + BD DC = 14 cm now we get two right triangles ABD and ADC IN A RIGHT TRIANGLE ADC we have, AC^2 =AD^2 + DC^2 AC^2 = 24^2 + 14^2 AC^2= 576+196 = 772 AC = square root of 772 = 27.8 cm |
