​

• ╰─➤ Mencari Rusuk ;

f(x) = 6x + 7x - 30

f(5) = 6(5) + 7(5) - 30

f(5) = (6.5) + (7.5) - 30

f(5) = 30 + 35 - 30

f(5) = 30 + 5

f(5) = 35

• ╰─➤ Mencari Volume

v = r × r × r

v = 35 × 35 × 35

v = 1.225 × 35

v = 42.875 satuan ✔️

Jawaban:

• cari sisinya dulu ygy

f(x) = 6x + 7x - 30

f(x) = 13x - 30

f(5) = 13(5) - 30

f(5) = 65 - 30

f(5) = 35

• Baru ges, cari volumenya

V = s³

V = 35³

V = 35 × 35 × 35

V = 42.875 satuan Volume
