Answer 1

Answer:

Volume = 10459.43cm³

l = 20cm

TSA = 3036cm²

Step-by-step explanation:

Volume:

22/7 x 16 x 1/3 [(8x8) + (20x20) + (20x8)]

22/7 x 16/3 (64 + 400 + 160)

22/7 x 16/3 x 624

219648/21 = 10459.43cm³ (approximated answer)

TSA:

l² = √h² + (r₁ - r₂)²

√(16x16) + (20-8)²

√256 + 144

√400 = 20cm (slant height)

22/7 x 20 (20+8) + (22/7 x 20 x 20) + (2/7 x 8 x 8)

1760 + 8800/7 + 132/7

1760 + 8932/7

1760 + 1276 = 3036cm²
