Jawaban:

1. B

2. B

Penjelasan dengan langkah-langkah:

V = π•r²•t

= 22/7•14•14•25 cm

= 22•2•14•25 cm

= 15.400 cm³

V = π•r²•t

= 22/7•21•21• 40 cm

= 22•3•21•40 cm

= 55.440 cm³

Answer 2

Jawaban:

Penyelesaian no 1.

• t = 25 cm
• d = 28 cm
• r = ½ × d
• r = ½ × 28 cm
• r = 14 cm

V = π × r² × t

V = 22/7 × 14² × 25

V = 22/7 × 196 × 25

V = 22 × 28 × 25

V = 15.400 cm³ (B)

Penyelesaian no 2.

• t = 40 cm
• r = 21 cm

V = π × r² × t

V = 22/7 × 21² × 40

V = 22/7 × 441 × 40

V = 22 × 63 × 40

V = 1.386 × 40

V = 55.440 cm³ (B)
