hitunglah volume bola jika diketahui jari jari 10cm diameter 35cm

r = 10 cm

Volume bola
= 4/3 x π x r³
= 4/3 x 3,14 x 10 cm x 10 cm x 10 cm
= 4.186,67 cm³

d = 35 cm
r = 17,5 cm

Volume bola
= 4/3 x π x r³
= 4/3 x 22/7 x 17,5 cm x 17,5 cm x 17,5 cm
= 22.458,33 cm³

Untuk r = 10


V1 = 4/3 pi r^3
= 4/3 (3,14) *10^3
= 4/3 (3140)
= 4186,66 cm^3

Untuk d = 35 cm
V2 = 4/3 pi (1/2d)^3
= 4/3 (3,14) ( 1/8 35^3)
= 4/24 (3,14)*42.875 cm^3
= 1/6 (3,14)(42.875 cm^3)
= 22.437,91 cm^3
