Question

Tolong jawab dong no 34-35 pke cara ya

Answer 1

34) t² = s² - r² = 5² - 3² = 25 - 9 = 16
t = √16 = 4 cm
v1 = 1/3 π r² t = 1/3 π × 3² × 4 = 1/3π × 9 × 4 = 12π cm³
v2 = π r² t = π × 3² × 12 = π × 9 × 12 = 108π cm³
v = v1 + v2 = 12π cm³ + 108π cm³ = 120π cm³
jawabannya : B

35)  t² = s² - r² = 39² - 15² = 1521 - 225 = 1296
t = √1296 = 36 cm
v1 = 1/3 π r² t = 1/3 × 3,14 × 15² × 36 = 1/3 × 3,14 × 225 × 36 = 8478 cm³
v2 = 2/3 π r³ = 2/3 × 3,14 × 15³ = 2/3 × 3,14 × 3375 = 7065 cm³
v = v1 + v2 = 8478 cm³ + 7065 cm³ = 15543 cm³
jawabannya : A
