if the digits are reversed, the new number is 45 more then the original number... 29 + 45 = 74.....not this because it does not = 92 38 + 45 = 83 <=====BINGO...ur number is 38....and the new number 83 (numbers reversed) is 45 more then 38
We know that [surface area of a sphere]=4*pi*r² r²=surface area/(4*pi) r=√[surface area/(4*pi)] surface area=450 in² r=√[450/(4*pi)]------> r=5.98 in------------> r=6 in
