If it's really 4 ft around then the circumference is 4 ft. English is not your first language, then?
The circumference of a circle with a radius of 4 ft is: 25.13 feet (r x 2 x Pi = circumference).
A circumference of 12.57 feet.
It is 8*pi = 25.13 ft, approx.
To find the circumference of a circle, which represents the linear feet around it, you can use the formula (C = \pi \times d), where (d) is the diameter. For a circle with a 4 ft diameter, the circumference is (C = \pi \times 4 \approx 12.57) feet. Therefore, there are approximately 12.57 linear feet in a 4 ft diameter circle.
It is 12.6 ft, approx.
Well, isn't that just a happy little question! To find the circumference of a circle, you can use the formula C = 2πr, where r is the radius of the circle. Since the diameter is twice the radius, if the circle has a diameter of 4 feet, the radius would be 2 feet. Plugging that into the formula, the circumference would be 4π feet.
Circumference is simply pi times the diameter. The approximate value of pi is 3.14, so for a circle 4 feet in diameter, the circumference is 4 x 3.14 = 12.56 feet, approximately.
Ther are 7.48 gallons in a cu ft tank is 3.14 x 4 x 4 /4 x 6 = 75.36 cu ft gallons = 7.48 x 75.36 = 563.7 gallons
It is 4/pi = 1.27 ft, approx.
The circumference of a circle can be found with this formula: Circumference = 2*(radius)*∏ where ∏ can be rounded to 3.14 Plugging in your radius of 4: Circumference = 2*4*∏ = 8*∏ which is around 25.13.
circumference ~= 18.9 ft area = π x radius2 ⇒ radius = √(area/π) circumference = 2 x π x radius ⇒ circumference = 2 x π x √(area/π) ⇒ circumference = √(4 x π x area) ⇒ circumference = √(4 x π x 28.3 ft2) ~= 18.858 ft
