Knowing that the formula to find the area of a circle is
* Ac = πr2 We must first find the radius of the circle with this formula:
* Rc = d/2 So dividing the diameter by two we get a radius of 20 feet.
* 20' = 40'/2 Now that the radius is found, we can plug it in and fine the exact answer needed:
* Ac = π(20ft)2 * Ac = π(400ft2) We find that the exact answer is 400πft2.
However if you want to calculate out the the value by multiplying out π the answer would change from 400πft2 to approximately 1256ft2. π = pi
π ≈ 3.14

What is the circumference of a circle with the diameter of thirteen feet?
About 40 feet. Circumference = 3.14 x diameter
If the perimeter of the table is 40 feet how long is the table?
If the table is a circle and the perimeter is 40 feet, then the diameter (rounded to 2 decimal places) would be 12.74 circumference = diameter x pi so, diameter = circumference / pi
What is the diameter of a circle is the area is 400pie?
area = pi x diameter squared/4 = 400 pi diameter squared = 4 x 400 x pi/pi = 1600 diameter = sqrt 1600 = 40
What is the area of a circle with a radius of 20cm and a diameter of 50cm?
This cannot be properly answered because a 20 cm radius equates to a 40 cm diameter. Also, a 50 cm diameter means a 25 cm radius.
If the diameter of a circle is 40 millimeters what is the length of the radius?
20 millimeters
How many square feet in a 40' diameter circle?
Area of circle: pi times radius squared
What is the area of a circle with a diameter of 40 ft?
Area = pi*202 = 1256.637 square feet to 3 d.p.
If the diameter of a circle is 40 m then what is the area in terms of pi?
If the diameter of a circle is 40 m then the area (in terms of Pi) is: about 400pi m2
What is the area of a circle with the diameter of 40?
A ≈ 1,256.64
How square feet in a 40 inch diameter circle?
Area of circle: pi*(20/12)^2 = 8.727 square feet rounded to 3 decimal places
What is the circumference of a circle with a diameter 40 FEET?
Circumference= PI x Diameter = 3.14 x 40 feet = 125.6 feet
What is the circumference of a circle with the diameter of 40 feet?
The circumference of a circle can be found using the formula C = πd, where C is the circumference and d is the diameter. In this case, the diameter is 40 feet. So, the circumference would be C = π(40) = 40π feet, or approximately 125.66 feet.
What is the area of a circle if the diameter is 40?
Using 3.14 as Pi the area of circle is: 1256.0
What is the diameter of a circle with a radius of 20 feet?
Diameter = 2 * radius So in this case, 40 feet.
How many square feet are in a circle 40 feet in diameter?
1256.64 square feet
Diameter of circle in inches if the radius is 20 feet.?
40'
