V ½ bola

$= frac{ frac{4}{3} times pi times {r}^{ 3} }{2}$

v ½ bola =

$frac{ frac{4}{3} times frac{22}{7} times {7}^{3} }{2} \ = frac{ frac{4}{3} times 1078 }{2} \ = frac{4312}{3} times frac{1}{2} \ = frac{2156}{3} = 718.67$

v kerucut =

$frac{1}{3} times pi times {r}^{2} times t \ = frac{1}{3} times frac{22}{7} times {7}^{2} times 24 \ = 154 times 8 \ = 1232$

V keseluruhan = 718,67 + 1232 = 1950,67 cm³
