You need to buy 14 bags.
area = pi * (13/2)^2 = 132.73... ft2
Circles have diameters, so we will assume from your question that it is a circular flower bed. Square feet is a measure of area. Cubed feet is a measure of volume. You need the area of the flower bed that has a diameter of 13 feet. To find the area of a circle you use the formula Area = pi * radius squared Pi is approximately 3.14 The radius of a circle is one half of the diameter of a circle. In your case 13/2 = 6.5 A = pi * r2 A = 3.14 * (6.5)2 A = 132.665 square feet
I'm pretty sure 25 pounds of fertilizer should do it.
The reason that manhole covers are round, and not square, is because a square cover could, when placed at the right angle, fall through the square hole in the ground. A circle, however, is the same diameter no matter where you measure it, and it cannot fir through a hole the same size and shape, no matter how hard anyone tried.
1 acre = 43,560 square feetYou need (43,560 / 5,000) = 8.712 bags.Buy nine.
5000.Area of a square = 0.5*(diameter)^2
You would need to buy 4 bags.
The fertilizer will cover a square plot 20 feet by 20 feet.
The 24 gallons of fertilizer covers 43,560 square feet (1 acre). Thus, you would only need about 0.07 gallons (about 9 ounces) to cover 120 square feet.
2 bags covers 5,000 square feet so you'll need 3 bags with enough fertilizer left over to cover 1,500 square feet.

Each circumference = 10m = (pi) x (each diameter)Diameter = 10/piSide of the square = 2 diameters = 20/pi = 6.366 meters(rounded)
http://www.rubberecycle.com/ I heard is selling $14 lb bags of Rubber Mulch! In all colors and the black ones are only $12! Each bag covers 13 square feet and 2 inches thick!
Its diameter is congruent to a side of square.
It is the length of the diameter multiplied by itself, with the units being the square of the units used for measuring the diameter.
