A circle with a diameter of 18 feet has an area of 254.5 square feet.

Area = 254 square feet.

If the diameter is 18 feet then the area is about 254.469 ft². If the radius is 18 feet then the area is about 1017.876 ft².

A circle with a diameter of 18 centimeters has an area of 254.47 square centimeters.

The area of a 18-inch diameter circle is: 254.5 square inches.

The area of a circle is equal to πr2 where π (pi) is equal to approximately 3.142 and r represents the radius of the circle. Because the question gives you the diameter and not the radius you have to use the measurement of the diameter to calculate the radius. Remember that the radius is equal to half the diameter. So if the diameter is equal to 18 feet, then the radius of this particular circle is equal to 9 feet. Plugging this into our equation for area we get: area = π(92) area = 3.142(81) area = about 254.5 ft2 (don't forget that the answer is in squared feet not just feet)

d = 5.73 feet.

The circumference of a circle is determined by multiplying the diameter (d) by the number pi. Therefore, the circumference of a circle with a diameter (d) of 18 feet is 18pi or 18x3.14159265358979323846... Roughly 56.54866776461627829228.

Assuming it is a circle, the area would be equal to 0.5*pi*(diameter)^2. For this circle, it would be 0.5*pi*6^2=18*pi, which is about 56.5486677646 square feet.

Diameter is twice the radius, so 18 feet.
