How do you convert the diameter of a circle to square ft.?
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

What is the area and the circumference of the circle when diamter is 6mm?
area = 9∏mm (approx. 28.26mm) circumference = 6∏mm (approx. 18.84mm)
How do you find the diamter of a circle if you know the area?
In order to find the diameter of a circle if you have the area is to rearrange the formula for the area of a circle to put diameter as the unknown, like so: PIE*d = Area of a Circle d = (Area of a Circle) / PIE Therefore if the area of your circle is 40cm, 40/PIE = 12.73cm and that's the diameter.
How do you find the area of a semi-circle in terms of pi?
The area of a full circle is pi x R squared where R = RADIUS The area of a semi circle is half of that, or pi x R squared/2
