You are installing a tank that measures 10 feet tall and 10 feet in diameter, you determine that the tank will hold gallons of water. the concrete guy that is pouring the foundation for the tank knows how much it weighs md but he needs to know how much the waterways when the tank is full. since 1 gallon of water weighs 8.34 pounds, you determine that the weight of the water

1)5875.882 gallons of water

2) 49004.85588 pounds

Step-by-step explanation:

Tank is like a cylinder.

Volume of cylinder = πr²h

r - radius of cylinder

h - height of cylinder

To find the volume of tank

Diameter d = 10 feet

r = d/2 = 10/2 = 5 feet

h = 10 feet

Volume of cylinder = πr²h = 3.14*5²*10 = 785 Cube feet

To find the gallons of water inside the tank

1 Cube feet = 7.48052 gallons

785 Cube feet = 5875.882 gallons

To find weight of water

1 gallon of water weighs 8.34 pounds,

5875.882 gallons = 8.34*5875.882 = 49004.85588 pounds

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
