3.14 is a rounded value for pi. You can find a more exact value, and online tools to allow you to multiply by pi through a search engine.

The diameter is twice the length of radius, so it is 28 feet.
Circumference = 2*pi*72 = 452.3893421 feet
The surface area of a circular based prism is (2pi x radius squared) + (2pi x radius x height)
The radius is the distance between the centre of a circular arc and a point on the arc.
How much fencing is required to enclose a circular garden with a radius of 14 meters? (Use 3.14 for π) _
176 m of fencing. Area of circle = 2*pi*radius
Fencing needed: 2*pi*18 = just over 113 meters
50 pi meters
Circumference=2pir=2x3.1416x30 ft=188ft Length of each side = circumference/4=188 ft/4=47 ft Answer: 47 feet
The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.
The diameter is twice the length of radius, so it is 28 feet.
the answer is $64.08
You will need 3.14 metres of fencing. You will need to ensure that the fencing is wire and not wood since you will need material which can be shaped into a pretty tight circle. The standard width of a wooden panel will be far too big: four of them in a square will cover an area more than 4 times what is required.
Approx 25.13 metres.
The radius of a circle is the distance from the center to any point on the circle's perimeter. For example, "The garden had a circular fountain with a radius of five feet."
If you want to find the size of your circular garden you will need a scientific calculator to do some sums. here are the methods.The area of the garden is equal to Pi times the square of the radius. To find the radius, measure from the edge of the circle to it's middle point, cutting a slice of cake.The circumference of the garden (the length of it's outer edge) is equal to Pi times it's diameter. To find the diameter, measure the length from one side to the other, cutting through the center point.
