Answer:
you need to times that if you want to calculate then do it y'll find the answer just use 3.14
16. 502.65 cm²
17. 628.32 dm²
18. 87.11 cm²
Step-by-step explanation:
16. V = π r² h
= π (4)(10)
= 502.65482
≈ 502. 65 cm²
= π (10)(2)
= 628.31853
≈ 628.32 dm²
16. V = 4/3 π r³
= 4/3 π (2¾)³
= 87.11375
≈ 87.11 cm²
