= 1540
V1/2 B =2/3.7.7.7
= 718,6666 (718,7)
VT + V 1/2B = 1540+718,7= 2.258,7 (B)
= pi . r² x 10
= 22/7 x 7² x 10
= 22 x 70
= 1540 cm³
volume 1/2 bola = 1/2. 4/3 . pi . r³
= 1/2 . 4/3 . 22/7 . 7³
= 1/2 . 4/3 . 22.49
= 4/6. 1078
= 718,7 cm³
volume ke2nya= 1540 +718,7
= 2.258,7 cm³
jadi jmlh volume kduanya adl 2.258,7 cm³
