How many Armstrong numbers in 0 to100000?
The Armstrong numbers from 0 to 10000 are 1,153, 370, 371, 407!! That's it Nothing more and nothing less ;) Let k be the number of digits in a number, n, and d1,d2,d3,d4... be the digits of n. Say n=370. Then k=3 and d1=3, d2=7 and d3=0. Now 33+73+03=370. So 370 is an Armstrong number. Armstrong iff n=d1k+d2k+d3k+d4k+...
How do you find the height and diametre of a 1000cm3 volume cylinder if the height and diameter are the same?
The volume of a cylinder is πr2h = 0.25πd2h where r is the radius, d the diameter (= 2r) and h the height. Now, h = d so V = 0.25πd3 = 1000cm3 So d3 = 4000/π = 1273.24 cm then d = cube root of 1273.24 = 10.84 cm (to 2 dp).
