I assume you mean 1 and 3/4 inches in diameter. Therefore your cross-sectional area of your hose is pi/4*diameter. You can either leave your diameter in inches or convert it to feet. If you choose to leave you number in inches then you convert 100 ft to 1200 in and multiple 1200*cross-sectional area to get the cubic inches water in the hose. If you choose to convert your diameter to feet then just multiply 100 ft times cross-sectional area to get the cubic ft of water in the hose.
A circle with a diameter of 14 feet 9 inches has an area of: 170.87 square feet.
The area of a circle is pi × r2. pi = 3.141592653589793 5 feet = 60 inches. The radius is half the diameter so the radius is 30 inches. If you plug 30 inches into the formula you get the answer of 2827.4333882308138 inches for the area of the circle.
The area of a circle with a diameter of 8 feet is: 50.27 square feet.
The area of a circle that has a diameter of four feet is: about 12.57 square feet.
