Question

Luas permukaan suatu bola adalah 314 cm kubik . maka volume bola tersebut adalah ?
tolong nah bantuan nya .

Answer 1

Verified answer

Luas bola = 4πr²
314 = 4×3,14r²
314 = 12,56r²
r² = 314/12,56 = 25
r = √25 = 5

v. bola = 4/3×πr³
4/3×3,14×5×5×5
4/3×3,14×125 = 523,33cm³

semoga membantu

Answer 2

4 phi r^2 = 314
r^2 = 25
r = 5

volume= 4/3 phi r^3
= (4 phi r^2) x 1/3 x r
= 314/3 x 5
= 1570/3
= 523 1/3
