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.
It is 12.6 ft, approx.
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.
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.
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.
It is 4/pi = 1.27 ft, approx.
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
Height cannot be calculated from the information given.
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
Assuming that the tank is cylindrical: Volume = ¶*r2*hKnowing this, the volume of the cylinder is 78.54 ft3.1ft3 = 7.48 US liquid Gallons.So... the tank will hold around 587.52 US liquid gallons.
