Penjelasan dengan langkah-langkah:

31. suhu setelah 30 menit= 32 -(30 : 6 x 3)

= 32 -(5 x 3)

= 32 - 15

= 17⁰C

32. yang disimpan= 30 - (30 x ¼ + 30x ⅔)

= 30 - (7,5 + 20)

= 30 - 27,5

= 2,5 m

33. s dari kerucut =√(a² + b²)

=√(15² + 20²)

=√(225 + 400)

=√625

=25

lp = πxrx(s+r) + 2xπxrx(r+t) - 2xπxr²

= 3,14x15x(25+15) + 2x3,14x15x(15+10)- 2x3,14x15x15

= 1.884 + 2.355 - 1.413

= 4.239 - 1.413

= 2.826 cm²

34. V = v1 + v2

= s³ + pxlxt

= 6³ + 15x8x6

= 216 + 720

=936 cm³

35. modus = 36 kg

modus adalah nilai terbanyak

median=34,34,34,34,35,35,35,35,35,35,36,36,36,36,36,36,36,36,37,37,37,38,38,39,39,39,39,39,40,40

= ½ x (36+36)

= ½ x 72

= 36 kg

semoga membantu
