Jawab:
16. = 3,14 . 900
17. = 15 . 14² + 10π.7²
18. =
19. median, antara 147 dan 148
20. = 40.6 -25-40-45-40-55
Penjelasan dengan langkah-langkah:
. = titik = kali
16. luas lingkaran = πr²
=π30²
=3,14 . 900
17. volume gabungan
jari jari = × 14
=7
Volume = 14.14.15 + π7².10
=15.14² + 10π7²
18. volume = 11200 cm³
tinggi =
19. nilai tengah = median
145,146,147,148,150,152
nilai tengah antara 147 dan 148
20. rata rata 6 bulan = 40 ton
25,40,45,40,55
40.6 = +25+40+45+55
= 40.6 - 25 -40 -45 -55
