Convert 600 mm into feet and use the formula: area = pi*radius2
2.2
circumference = diameter x pi area = radius squared times pi divide circ with pi gives you the diameter diameter/2 gives you radius radius times itself times pi gives you the area get the units right and you're done.
Diameter is half of the radius. Times it by 2.
If you want the area of a circle, and you know the diameter, then: A = pi*r^2, where r is the radius, and is 1/2 the diameter, so pi*(diameter/2)^2 = (pi/4)*(diameter)^2. If you want square inches, then make sure you have the diameter measurement in inches, first.
To convert diameter to area , you will need to divide the diameter by two so as to get the radius. The result you get, square it and them multiply it by 3.14 to find the area.
if it was a circle it would be about 153.86 square meters.

Convert 600 mm into feet and use the formula: area = pi*radius2
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.
when trying to find squ. feet you have to find the area. the area of a circle is half of the diameter squared times pi half of the diamter is the radius therefore the area in squ. ft would be.. A = pi x r2

50 diameter to length
circumference = diameter x pi area = radius squared times pi divide circ with pi gives you the diameter diameter/2 gives you radius radius times itself times pi gives you the area get the units right and you're done.
Diameter is half of the radius. Times it by 2.
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
If you want the area of a circle, and you know the diameter, then: A = pi*r^2, where r is the radius, and is 1/2 the diameter, so pi*(diameter/2)^2 = (pi/4)*(diameter)^2. If you want square inches, then make sure you have the diameter measurement in inches, first.
