How many gallons of water to fill a 25' diameter x 4' deep pool?
14,700 gallons, based on the calculation of the area of a Circle (pi * radius squared) times the depth (4 feet) times the number of gallons per cubic foot (7.5)
How many gallons of water does it take to fill a round 18ft pool that is 52 inches deep?
shall assume the 18ft measurement is the diameter, not radius. 18ft = 5.486m = diameter 52in = 1.321m = depth pi x radius(squared) = area of the circle pi x 2.243(squared) = 15.8055 meters squared area x depth = volume in meters cubed 15.8055 x 1.321 = 20.879 meters cubed 1 meter cubed = 1000L 20.879 meters cubed = 20879L 20879L is: 5515.648 US Gallons 4592.738 UK Gallons
What is the perimeter of a circle?
the radius2 x pi x r where pi = 3.1416To find the perimeter you do pi (3.1415) times the diameter.Or you can figure by the radius (P=2 π r; i.e. Perimeter = 2 x 3.1415 x radius)The perimeter of a circle is its circumference. We use these formulas to find the circumference of a circle; C=d times pi or C=2 times the radius times pi (3.14).To make it easier to explain:Area: Pi (3.14) X Radius Squared (r 2) from the center out of the circlePerimeter: Pi (3.14) X Diameter (d) from one side of the circle to the otherThe perimeter of a circle is called Circumfrence.Here is the formula for Circumfrence:C= pi x d (pi times diameter)C= 3.14 x ______ (fill in the blank with the diameter of the circle)C= (your answer)NOTE: Pi is equal to 3.14 so when you are using pi to multiply, replace it with 3.14When the diameter is not given in a circle, double the radius to find the length of the diameter.The perimeter of a circle is its circumferenceThe perimeter of a circle is its circumference

What is the area of a circle if the diameter is 4.4cm?
Since the area of a circle can be represented by the equation A=πr², to find the are of a circle you merely need to fill in the variables. The radius is half of the diameter, so a circle with a diameter of 4.4 cm has a radius of 2.2 cm. A=π(2.2)². First, square 2.2 and you will get 4.84. Then, multiply 4.84 by pi and you will get approximately 15.2. The area of a circle with a diameter of 4.4 cm is approximately 15.2 square cm.
What is the area of a circle with a circumference of 37.14?
To find the circumference of a circle, you use the formula C = 2∏r. You will need to use this equation to solve for r, the radius. Once you have the radius, you will then plug it into the formula for an area of a circle, which is A = ∏r2. Now, let's fill in your information.C = 2∏r37.14 = 2∏rDivide both sided by 2∏ to isolate the variable r.37.14/2∏ = rSince the original problem uses two decimal places, we will round to two decimal places as well.5.91 = rNow, that we have the radius, 5.91, we can fill it into the formula for an area of a circle to solve your problem.A = ∏r2A = ∏(5.91)2A = ∏(34.94)A = 109.77So, the area of a circle with a circumference of 37.14 is 109.77.
How many gallons fill a 13ft pool that is 3 feet deep?
The answer is about 2,979 gallons if you fill the pool exactly 3 feet deep. To get the answer you figure out the square feet in the 13 foot circle using the formula: Area = Pi times radius squared Pi is approxametly 3.142 Radius is 6.5 6.5 X 6.5 X 3.142 = 132.7495 square feet 132.7495 X 3= 398.2485 cubic feet 1 cubic foot holds 7.48 gallons 7.48 X 398.25= 2,978. 91 which rounds up to 2,979 gallons
How many 30cm squared tiles will fill an area of 30 meters squared?
id say 10.000
How do you fill circle with triangle?
you cannot because a triangle has verticles and a circle does not
How do you complete a circle graph?

How much soil is needed to fill a cylinder that is 3.5 feet tall and has a diameter of 32 inches?
Approximately 33,778.4042 inches cubed/to the third power.the formula for volume of a cylinder is pi x radius squared x height.
How many gallons does it take to fill a 24ft round by 4ft deep pool?
The volume of a right circular cylinder is computed by the equation: volume = pi * radius squared * height In your case: radius = 12 ft, squared it equals 144ft squared height = 4 ft pi = 3.14159........ This will get you volume in cubic feet, the conversion factor from cubic feet to gallons is: cubic foot * 7.4805 = gallon Put it all together: Volume = 3.14159 * 144 * 4 * 7.4805 and you get: 13,536.4 gallons Which is a lot of water.
