A. 18.750 cm3b. 37.500 cm3c. 37.680 cm3d. 75.360 cm3

Jawaban:

c. 37.680 cm³

Penjelasan dengan langkah-langkah:

V= 1/3 × pi × r²× t

V= 1/3 × 3,14 × (30 cm)² × t

Wait, tnya belum ada.

Oh tapi ada s, kita bisa manfaatkan.

(50 cm)²= (30 cm)²+t²

2500 cm²= 900 cm²+t²

t²= 1600 cm²

t= 40 cm

V= 1/3 × 3,14 × 900 cm² × 40 cm

V= 3,14 × 300 cm² × 40 cm

V= 942 cm² × 40 cm

V= 37680 cm²

Jawaban:

C. 37.680

Penjelasan dengan langkah-langkah:

$t = sqrt{ {50}^{2} - {30}^{2}} \= sqrt{2500 - 900} \ = sqrt{1600} = 40 \ v = frac{1}{3}pi : {r}^{2} t \ = frac{1}{3} times 3.14 times {30}^{2} times 40 \ = 37680$
