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

How many square feet are in a 40 foot diameter circle?

Oh, dude, you're hitting me with some math here! So, the area of a circle is π times the radius squared. If the diameter is 40 feet, the radius is 20 feet. Plug that into the formula, and you get an area of 400π square feet. But who's really counting, right?


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 circumference of a circle with a diameter 40 FEET?

The circumference of a circle can be calculated using the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. Given a diameter of 40 feet, we can plug this value into the formula to find the circumference: C = π(40) = 3.14159(40) = 125.6636 feet. Therefore, the circumference of a circle with a diameter of 40 feet is approximately 125.66 feet.
