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
