Since we are trying to calculate the number of cubic yards, let's calculate everything in terms of yards.

Converting inches to yards, we have to divide by 36, since there are 36 inches in a yard.

1 ' = 1/36 yard

Converting square feet to square yards, we divide by 9, since there are 9 square feet in a square yard.

3700 square feet = 411 square yards

Calculating cubic yards, we multiply 411 square yards by 1/36 of a yard.

I get 11.42 cubic yards. So you are safe getting 12 cubic yards.

Good luck,

Paul

area formula is PI x r squared

that is 3.1417 times the radius of the circle squared

example is:- 3.1417 times 3 inches squared =3.1417 times 3x3=3.1417x9=28.279 square inches if you want to work back from a circumference measurement, the formula for circumference is 2 x PI x radius or PI x diameter

if you have a circumference of 12 inches then the dia is calculated 12 inches = dia x PI to get the diameter , divide the 12 inches by PI and that will be the diameter so that is 12 divided by 3.1417 =3.819 inches

now you can go from the first formula the radius is the diameter divided by 2 so the radius will be 3.819 divided by 2 = 1.909 inches

so applying the area formula it becomes 3.1417 times 1.909 times 1.909 =11.458 square inches

to find your answer simply substitute the dimensions in place of the example figures.in the relevant formula.

Answer is A. Divide area by pi to find the circumference. (153.86/3.14 = 49) Determine the square root of the circumference to find the radius. (sqrt of 49 = 7)

drive a peg in the ground where you want the center of the circle to be

get a piece of string and make a loop at one enf big enough to fall over the peg

measure out 3 ft from that loop and tie a stake at that point

now pull the string until it is tight and where the peg hits the ground make a mark

move about a foot an make another mark keeping the string tight all the whole

repeat the process until you have done a complete circle

the marks will be the circumference of a 6 foot diameter circle

If you would like to know the circumference of a 15" diameter circle this is the formula:

circumference = radius x 2 x pi

circumference = diameter x pi

in our case:

circumference = 15" x 3,14

circumference = 47 ,1" (that's 119,634 cm)

circumference = radius x 2 x pi

circumference = diameter x pi

in our case:

circumference = 15" x 3,14

circumference = 47 ,1" (that's 119,634 cm)

The circumference of any circle is pi (lowercase Greek letter pi) multiplied by the diameter. For a four-foot diameter circle the circumference is about 12 feet 7 inches.

Multiply 9ft by 2ft by 2ft to get 36 cubic feet. One foot is exactly 0.3048 meters so one cubic foot is about 0.0283 cubic meters. Multiply that by 36 to get about 1.019 cubic meters.
