Multiply the diameter of the cylinder in feet by pi. (3.141592652), then multiply that answer by the length of the cylinder in feet.
There are linear feet, and square feet, but no "linear square feet".
to calculate square feet you need a 2d shape
Square meters x 10.764 = square feet.
Square inches x 0.00694 = square feet
You can't actually go from feet to square feet because feet is distance but square feet is area. but to calculate for example the square feet in a rectangle you would do base times height.

Multiply the number of square meters by 10.7639 to get square feet.
Multiply acres by 43,560 to get square feet.
Square feet divided by 43,560 = acres
There are 9 square feet in each square yard. You multiply the yards by 9 to get the feet.
An acre is 66 x 660 feet, or 43560 square feet. Multiply that by 13, then calculate the square root of the result.An acre is 66 x 660 feet, or 43560 square feet.
