Assuming you mean 28ft x 28ft x 6ft you would need 174 2/9 yards of concrete, assuming no waste.
Circumference of the pool = 28*pi feet
Let's compare them by using their equivalents in feet: 1,000 yards = 3,000 feet 1,000 meters = 3,280.8 feet
125 feet = 125/3 yards = 41 2/3 yards (or 41.6667 yards)
There are 15 yards in 45 feet. 45 feet x 1 yard/3 feet = 15 yards 1 yard = 3 feet
Assuming you mean 28ft x 28ft x 6ft you would need 174 2/9 yards of concrete, assuming no waste.
To find the square feet of a room, you are just finding the area. Area is length times width. So, in a room with dimensions 28 by 28 feet, the square feet is 784.
28 feet is 336 inches.
Circumference of the pool = 28*pi feet
20ft x 28ft = 560ft2
7 and a half feet, acording to my calculations.
Let's compare them by using their equivalents in feet: 1,000 yards = 3,000 feet 1,000 meters = 3,280.8 feet
125 feet = 125/3 yards = 41 2/3 yards (or 41.6667 yards)
There are 15 yards in 45 feet. 45 feet x 1 yard/3 feet = 15 yards 1 yard = 3 feet
It isn't unless you're using a different definition for yard. 2.5 yards = 7.5 feet < 8 feet
There are 9 feet in 3 yards. 3 yards x 3 feet/1 yards = 9 feet 1 yards = 3 feet
There are 6300 feet in 2100 yards. 2100 yards x 3 feet/1 yards = 6300 feet 1 yards = 3 feet
