Question

I need help to solve these two problems step by step

Answer 1

hope this helps! :)

Explanation:

1.) Surface Area = 2 × (5 × 2 + 5 × 3 + 2 × 3) = 62 inches2

Volume = 5 × 2 × 3 = 30 inches3

3.) Base Surface Area = π × 282 = 2463.0086404144 miles2

Lateral Surface Area = π × 28 × √282 + 1002 = 9134.774768285 miles2

Total Surface Area = 11597.783408699 miles2

Volume = 1/3 πr2h = 1/3 × π× 282 × 100 = 82100.288013813 miles3
