Teladan Soal Volume Bola Beserta Pembahasannya

Latihan Soal Volume Bola Soal No.1 Hitunglah volume bola yang mempunyai jari-jari 4 cm ? Pembahasan jari-jari (r) = 4 cm

Volume Bola =

4 / 3

x π x r³
Volume Bola =

4 / 3

22 / 7

x 4³
Volume Bola = 268,19 cm³

Soal No.2 Sebuah jeruk yang berupa bola mempunyai diameter 3 cm. Lalu anda memotong kedua jeruk tersebut sama besarnya. Hitunglah volume setengah jeruk tersebut (π = 3,14) ? Pembahasan d = 3 cm
r = 1/2 d = 1,5 cm

Volume Jeruk =

4 / 3

x π x r³
Volume Jeruk =

4 / 3

x 3,14 x 1,5³
Volume Jeruk = 14,13 cm³

Volume

1 / 2

Jeruk =

1 / 2

x 14,13 cm³
Volume

1 / 2

Jeruk = 7,065 cm³

Soal No.3 Sebuah bola kasti yang berupa bola memiliki volume 113,04 cm³. Hitunglah diameter bola kasti tersebut (π = 3,14) ? Pembahasan Volume Bola Kasti = 113,04 cm³

Volume Bola Kasti =

4 / 3

x π x r³
113,04 =

4 / 3

x 3,14 x r³
113,04 x 3 = 4 x 3,14 x r³
339,12 = 12,56r³
r³ =

339,12 / 12,56

= 27
r = 3 cm

d = 2r = 2(3) = 6 cm

Makara diameter bola kasti tersebut yakni 6 cm

Soal No.4 Hitunglah volume bola bowling dalam satuan cm³ jika dikenali jari-jarinya adalah 2 inch (π = 3,14) ? Pembahasan jari-jari bola bowling (r) = 2 inch

Volume Bola Bowling =

4 / 3

x π x r³
Volume Bola Bowling =

4 / 3

x 3,14 x 2³
Volume Bola Bowling=

4 / 3

x 3,14 x 8
Volume Bola Bowling =

4 / 3

x 25,12
Volume Bola Bowling =

100.48 / 3

Volume Bola = 33,49 inch³

Langkah berikutnya konversi cm³, dimana :
1 inch³ = 16,3871 cm³ maka :
33,49 inch³ = 54880,277 cm³

Makara Volume Bola Bowling = 54880,277 cm³
