Convert 600 mm into feet and use the formula: area = pi*radius2

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.
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.
You don'tPerhaps your question is very poorly articulated. You don't "convert" a diameter to "square feet." You calculate a circle's area (in square feet) if you know its diameter (in feet) and the formula for the area of a circle.The area of circle is given by the formula A = (Pi)r2, where r is the radius of the circle. Note that the radius is one half the diameter: r = d/2.We can then derive a formula for area as a function of the diameter:A = (Pi)r2 = (Pi)(d/2)2 = (Pi)d2/4 or (1/4)(Pi)d2.When using the formulas, you must be certain that your units are consistent. If your diameter is in feet, then your answer will be in square feet.Note that you can use Pi = 3.14 for most routine calculations.Actually, you can use a diameter in inches and get an area in square feet. The constant is 0.005454. So, the area equation is converted to look like thisA=0.005454d2you do not have to get an answer in the same unitsalso, the same applies for the metric systemA=0.0000785d2for this, you can put in a diameter in centimeters and get square metersSo sorry man, but you can indeed get an area that is in a different unit.AddendaThe fact remains that the diameter of a circle is a linear measurement and cannot be converted to an area or square measurement. Knowing the diameter you can find the area of the circle and using various manipulations convert it to the desired system of units.
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

To find the number of acres in a 2114 feet circumference, you need to first convert the circumference to a diameter. You can divide the circumference by Pi (3.14159) to get the diameter. Once you have the diameter, you can use the formula for the area of a circle (A = πr^2) to find the area in square feet. Finally, convert the square feet to acres by dividing by 43,560 (since 1 acre is equal to 43,560 square feet).
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.
