Area in square feet = pi*62
9pi (about 28 and one quarter) square feet.
First find out the radius (it is simply half the diameter). Then use the formula area = pi x radius2.
Circumference= 3.14 x Diameter Area of circle= 3.14 x diameter x diameter
A semicircle is 1/2 of a circle. Find the area with the diameter you are given as if you had a whole circle, then divide that answer by 2 to get the area of the semicircle.

A = 804 square feet.

First find out the radius (it is simply half the diameter). Then use the formula area = pi x radius2.
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
Circumference= 3.14 x Diameter Area of circle= 3.14 x diameter x diameter
A semicircle is 1/2 of a circle. Find the area with the diameter you are given as if you had a whole circle, then divide that answer by 2 to get the area of the semicircle.
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
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.
Diameter is 8.64444
The area of a circle with a diameter of 6 units is: 28.27 square units.
The circumference of a circle is pi * the diameter. The diameter is radius * 2. The area of a circle is pi * the radius squared. So for a circle of circumference 62.8 ft, the radius is 62.8/pi/2 which is 10.0 ft to 1 decimal place The area is pi * radius squared = 314.2 sq ft.
