find the width of a rectangle if its area is 9/28 of a square foot
There are 9 square feet in a square yard. This means to find price per square foot given price per square yard, division by 9 is in order. $11.69 divided by 9 = $1.298888... or about $1.30 per square foot.
Total surface area of a cylinder = (2*p*radius2)+(pi*diameter*height)Total surface area = 1130.973355 or 1131 square feet to the nearest square foot.
A roll 2 foot by 30 foot contains 60 square feet. There are 144 square inches in a square foot. So the roll contains 8630 square inches = and you get all of these for 30 units of currency. I will assume that the unit of currency contains 100 smaller units. so the price is 3000 small units. This means that the cost per sq inch = 3000/8630 = 0.347 small units = just slightly more than one-third of the small unit.
