= πr²t + 1/3πr²t
= 22/7 x 14² x 12 + 1/3 x 22/7 x 7² x 10
= 7392 + 513,33
= 7905,33 cm³
= 22/7 x 14 x 14 x 12
= 22 x 2 x 14 x 12
= 7392 cm³
V. kerucut = 1/3 πr²t
= 1/3 x 22/7 x 7 x 7 x 10
= 1/3 x 22 x 7 x 10
= 1/3 x 1540
= 513,33 cm³
V. total = V. tabung + V. kerucut
= (7392 + 513,33) cm³
= 7905,33 cm³
