g100num [7]

Answer:

  • 100 minutes

Solution:

<u>We know that:</u>

  • Capacity = 2,500 gallons
  • Hose = 25 gallons/minute

Solution:

  • 25 gallons = 1 minute
  • => 25x gallons = x minutes = 2500 gallons
  • => 25x = 2500
  • => x = 100 minutes

Hence, it will take 100 minutes to fill the pool.

find the circumference of a circle that has an area of 452.16 square meters. (Use 3.1416 as the value of π.)
IceJOKER [234]
(1) circumference of a circle = 2π.R
(2) area of a circle = π.R²

Area = 452.16 m² (given), so we can calculate the radius:
452.16 = π.R²
452.16/π = R²

143.92 = R²  → R =√143.92 ≈ 12 m
Having R = 12, now we can calculate the circumference :

circumference of a circle = 2π.R = 2.π.12 = 75.41 m
