Circumference (perimeter) = pi * diameter = 3.141592654 * 21 = 65.973 feet
Surface area = pi * radius 2 = 3.141592654 * 10.5 * 10.5 = 346.36 sq. feet
Volume (cu feet) = 346.36 * depth in feet
.
Volume * 7.4805 = US gallons
Volume * 6.2288 = imp gallons
(results approximate)

Diameter to radius?
Diameter- A line going straight from side to side of a circle, equals the total distance across the circle. Radius- Half of the total diameter. For example, if the diameter is 8, the radius is 4.
How many numbers total are in pi?
Pi is endless. Nobody can determine where the end is.
Is circumference and diameter the same?
No.Circumference is the total distance around a plane figure. Usually a circle or ellipse.Diameter is the distance of a straight line from edge to edge passing through the centre of a circle.
What is the number of degrees in an arc of a circle?
It depends on the length of the arc because there are a total of 360 degrees in a complete circle.
What is the raduis of a circle that is inside a square with an area of 400 cm?
Assuming the circle is tangent to the sides of the square, then the edges of the circle meet the square at the midpoint on each of the four sides. So the diameter of the circle is the same as the length of a side of the square. So all you need to do is find the length from the total area by taking the square root of the area (since A = s2), which gives you the diameter, then halve it to get the radius.
What is the total diameter of a circle?
It is twice the size of a circle's radius.
Diameter to radius?
Diameter- A line going straight from side to side of a circle, equals the total distance across the circle. Radius- Half of the total diameter. For example, if the diameter is 8, the radius is 4.
How many square feet in a circle that is 52 feet in diameter?
The formula for the area of a circle is pi (3.141265...) times the radius squared. Since half of the diameter is the radius, plug that number into the formula to get the total square feet.
What is the formula to calculate Pitch circle diameter?
Better known as Bolt Circle Diameter, the formula is d / sin (1/n x 180) where d is the distance between the centers of two adjacent bolts and n is the total number of bolts.
What is 1 yard in diameter?
The diameter of a circle is from one point-to the other (a straight line) in a circle(<---->), So in 1 yard being the total distance in length <----1yard--->, the diameter is 1 yard.
What is the diameter and circumference of a circle?
It depended on how much is the diameter in total then you divide it by pi. Pi means-3.14 that is how you get the radios
How many numbers total are in pi?
Pi is endless. Nobody can determine where the end is.
If a circle has a diameter of 30 feet how many feet is the total perimeter?
30 * pi ≈ 94
What is whole round circle?
In a circle, 360 degrees are the total number of degrees.
What is the area of a circle with diameter of 34 feet?
The formula for the area of a circle is: A=∏r2Where A is the total area of the circle and r is its radiusThe diameter is twice the radius, so the radius in this case would be 17 feet.A=∏*(17)2A=∏*289A=289∏A equals about 907.46 feet
If Earth was a circle how long would its diameter be?
The total surface area of the Earth is 5.1 × 108 km2. so 4(pi)r2 =surface area of a circle. solve for (r). r = 6372.2 km diameter = 2r =12744.4 km
Is circumference and diameter the same?
No.Circumference is the total distance around a plane figure. Usually a circle or ellipse.Diameter is the distance of a straight line from edge to edge passing through the centre of a circle.
