minta tolang jawab mengunakan cara

d = 14 cm ; r =7 cm

Volume tabung = π r² t
=[tex] \frac{22}{7} [/tex] x 7 x 7 x 20
=154 x 20 = 3.080 cm³
t=44-20=24
Volume kerucut = 1/3 x π r² t
=1/3 x[tex] \frac{22}{7} [/tex] x 7 x 7 x 24
=1/3 x 154 x 24
=1/3 x 3.696
=1.232cm³
Volume tabung+kerucut =3.080 cm³ + 1.232cm³ = 4.312cm³

jawabannya (A). 4.312cm³
