Square footage (surface area) of a 36 inch diameter sphere = 4pir2 pi = 3.1416 r = 1/2 X diameter You asked for square footage; so first convert 36 inches to feet 36 inches / 12 inches/foot = 3 feet r = 1/2 X 3 feet = 1.5 feet surface area = 4 X 3.1416 X (1.5 feet)2 = 28 square feet
To calculate the square footage, we need everything in feet or in inches. Since we are going to end in square feet, it is easiest to convert everything to feet first. 7 inches is equal to 7/12 feet, since there are 12 inches in a foot. 4 feet and 7 inches is equal to 4 and 7/12 feet, or 55/12 feet if you make it into an improper fraction. Then you simply multiply 7/12 and 55/12 together to get the square footage, which would be 385/12 feet, or 32 feet and 1 inch.
That is 240 square inches. There are 144 square inches in a square foot therefore it is approximately 1.66 square feet.
Diameter = 20 inch => radius = 10 inches = 10/12 feet. So area = pi*(10/12)^2 = 2.1817 sq feet approx.
625 inches = 1,587.5 centimeters.
Square inches to square feet: divide by 144.
There are 144 square inches in a square foot. There would be 7,200 square inches.
19 feet 1 inch by 21 feet 10 inches = 416.65 square feet.
7 feet 6 inches by 14 feet 1 inch = 105.625 square feet.
You can do one of the following to calculate this: 1) Convert inches to feet. Then multiply to get the area in square feet. 2) Multiply first, to get the area, but this time in square inches. Divide the square inches by 144 to convert to square feet.
The simplest way to answer a question like this is to convert the inch measurements to feet and then multiply. Dividing each measurement by 12 will convert inches to feet. Then multiplying length by width gives you the actual square footage. IE: 84/12=7 96/12=8 7x8=56 56 Square Feet
40inch = 3.33 foot 48 inch = 4 foot so 4 x 4 x 3.33 = 53.328 or 53 and a third cubic feet - as you have three measurements it needs to be in cubic feet either that or the pallet square footage is based only on 40 x 48 3.33 x 4 = 13.32 square feet
