Volume of a cylindrical tank 8 feet in diameter and 8 feet tall is pi x 16 square feet (radius squared) x 8 feet (height) = 402 cubic feet.
The question is mis-specified. You ask for the area but give the dimensions for volume.
"Feet" and "square feet" don't convert to each other. If they could, then you'd be able to figure out how many square-feet tall you are.
You measure the roof to get the square feet. There are 100 square feet in a square. On a straight single peak roof it's height times length on one side and double it. Then divide the total square feet by 100. This final number will give you the number of squares you have. If the roof is a flat, commercial roof, it is the same (100 sq. ft = 1 SQ). However, if it is a metal panel commercial roof, you need to add in "stretch factor" or the added amount of square footage if the panels were to be stretched flat. A good estimate for this is: If the ribs on the metal panel are 1" tall, add 10% to your square footage; if the ribs are 1.5" tall, add 15% to your total square footage. So, if you have a metal roof that is an R-panel (_/-\_), the ribs are 1.5" tall and the roof is 100 SQ (or 10,000 sq ft), take 10,000 sq ft + 15% (1500) = 11,500 sq ft (115 Squares).
4*pi = 12.6 cubic feet.
6,084*pi cubic feet or about 21,364.56 cubic feet.
Its total surface area is 15614 square feet.
The square footage is the footprint: length times width. 7521 square feet.
To get the area you multiply the length and the width. Doing the math gives an answer of 2,560 square feet.
If you are looking for the square footage of the room, the height shouldn't make a difference. So the square footage would just be 10 ft x 10 ft = 100 square feet. If you are looking for surface area of all the walls, floor, and ceiling, that would be 100+100+80+80+80+80 = 520 square feet If you're looking for the cubic footage of the room, then you would use all three dimensions. 8ft x 10ft x 10ft = 800 cubic feet.
The answer depends on whether the shape is a cylinder of a cone (or something else).
the square
Floor and ceiling = (9 x 8) = 72 square feet each Two walls = (9 x 7) = 63 square feet each Other two walls = (8 x 7) = 56 square feet each Total area on all six surfaces inside the room = 382 square feet
The height of the room doesn't matter, so it's just the length times the width, or 21 x 15.
You cannot. Height is a one-dimensional measurement. Square feet are two-dimensional. To get from height to square feet you must include another dimension... usually width. I am 6 feet tall - that is my height..... I don't have square footage, and my height cannot be converted to square feet. However, the door of the room I'm in is 6 feet 6 inches high, and is 3 feet 6 inches wide - which tells me that the surface area of the door is 22.75 square feet.

A square will always be larger than a circle with the same diameter. Draw a square, then draw a circle that fits inside the square exactly (that is, each of the four points shared by the two shapes exactly bisect each line of the square). The square contains the entire circle, plus all the extra area in the corners.
