The cylindrical swimming pool contain 4512 gallons of water, if a pool diameter has a diameter of 16 feet and a height of 3 feet.
Step-by-step explanation:
The given is,
Diameter of swimming pool is 16 feet
Height of swimming pool is 3 feet
Step:1
Formula for volume of cylinder is,
........................(1)
Where, r - Radius
h - Height
Formula for radius,
=
r = 8 feet
Step:2
From equation (1)
V cubic feet
Step:3
From given ( 1 cubic feet = 7.5 gallons )
V ≅ 4524 gallons
Result:
The cylindrical swimming pool contain 4512 gallons of water, if a pool diameter has a diameter of 16 feet and a height of 3 feet.
4512 mark me as brainliest pls!

The cost of one doughnut is $0.75 and the cost of one cookie is $0.60.
The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Alexandra buys two doughnuts and three treats at a donut shop and is charged $3.30. Brianna buys five doughnuts and two treats at a similar shop for $4.95. Every one of the doughnuts and treats has a similar cost.
Assume 'x' is the cost of doughnuts and 'y' is the cost of one cookie. Then the equations are given as,
2x + 3y = 3.30 ...1
5x + 2y = 4.95 ...2
Multiply equation 1 by 5 and equation 2 by 2, then we have
10x + 15y = 16.50 ...3
10x + 4y = 9.90 ...4
Subtraction equation 2 from equation 1, then we have
15y - 4y = 16.50 - 9.90
11y = 6.60
y = $0.60
Then the value of 'x' is given as,
2x + 3(0.60) = 3.30
2x + 1.80 = 3.30
2x = $1.50
x = $0.75
The expense of one donut is $0.75 and the expense of one treat is $0.60.

PLEASE HELP ME for 13 points!:) and thank you
1. Round 24 to 20 and 15 to 20. 20*20=400. True product is 360.
2. Round 37 to 40 and 63 to 60. 40*60 is 2400. True product is 2331.
3. Round 384 to 380 and 45 to 50. 380*50=19000. True product is 17280
