Pls Help You have a cone with base diameter of 12 cm and a height of 8cm. (Part 1) If the cone has its tip pointing downward and water is poured into the cone up to a height of 7cm, what percent of the cone is filled with water?

(Part 2) If the cone’s base is sealed so water cannot leak out and then the cone is flipped so that its tip is pointing upward, then what will the height of the water be?

546

Step-by-step explanation: 545 plus 1

approximately 5 hours 32 minutes

let x be the amount of it takes both pumps to fill and 1 pump to empty

so the pumps fill/empty at the rate of per hour

first pump fills at a rate of per hour

second pump fills at a rate of per hour

third pump empties at a rate of per hour

together the reservoir fills at a rate of

+ - =

multiply each term by 720x

120x + 90x - 80x = 720

130x = 720 ( divide both sides by 130 )

x = = 5. hours

(0. × 60 ≈ 32 minutes )

time taken to fill reservoir is 5 hours 32 minutes
