624,531 The answer is 625,000 463,356 The answer is 460,000
Always remember when rounding numbers, look to the right of the number you are rounding. If the number to the right is 5 or more round up. If its is 4 or less you round down. I hope this helped. :)

To round the numbers 624,531 and 463,356, you determine the underlined digit and look at the following digit to decide whether to round up or down. In this case, 624,531 rounds to 625,000 and 463,356 rounds to 460,000. This follows the standard rounding rules: round up if the next digit is 5 or more, and do not round up if it is less than 5.

Jawaban:Diketahui:Bentuk tugu = tabung + setengah bolaLuas yang dicat = luas selimut tabung + luas setengah bolaCat: 1 m² → ¼ kgπ = 22/7Misal r = jari-jari, t = tinggi tabungLuas total:= 2πr × t + 2πr²= 2πr(t + r)Jumlah cat:= ¼ × (2πr(t + r))= ½ × πr(t + r)= ½ × 22/7 × r(t + r)= (11/7) × r × (t + r) kgSemoga membantu ya!
