Answer:

Înălțimea bazinului este de 20 m

Step-by-step explanation:

Raza de bază a bazinului cilindric = lățimea peretelui dreptunghiular = 15 m

Suprafața peretelui dreptunghiular = lungime × lățime = 300 m²

300 m² = lungime × 15 m

lungime = 300 m² / 15m

lungime = 20 m

Lungimea peretelui dreptunghiular = înălțimea bazinului cilindric = 20 m

Prin urmare, înălțimea bazinului = 20 m.

Let the number of years after 2001 be x, then
1280000 + 19500x = 1700000
19500x = 1700000 - 1280000 = 420,000
x = 420000/19500 = 22 years.
x = 22 years.
