Circumference (the number I assume you want) = Pi X D C = 3.14 x 30 C = 94.2 There are 94.2 linear feet in a 30 foot diameter circle.
The floor is 30 square feet.So is the ceiling.
Feet and linear feet are the same measurement. Therefore, 30 feet is equal to 30 feet.
Multiply the 30 by 30.48 (cm per linear foot) and you get 914.4 cm. 914.4 squared is 836127.36 cm2. Divide that by 10,000 (cm2 per m2) and your answer is 83.612736 m2.
There is no answer. Square feet are a measure of area. Linear feet are a measure of distance. They are totally different things. You can only convert between measures of the same thing, e.g. 1 square foot = 144 square inches and both are measures of area.
Without a second measurement of width, there is no way of knowing. Linear is length and square foot is area. You have to know length and width to figure it. 30 linear feet 1 foot wide would be 30 square feet.
A linear foot has no width, so no matter how many you have of them, you will never cover a 32 x 30 space.

To find the linear feet needed for 30 square feet of material that is 2 feet wide, you would first calculate the total area in square feet, which is 30 square feet. Then you would divide the total area by the width (2 feet) to find the length in linear feet. In this case, with a material that is 2 feet wide and 96 inches long, you would need 15 linear feet for 30 square feet of material.
70' x 30' = 70*30 square feet = 2100 sq feet.
60 x 30 = 1,800 square feet
30 X 15 = 450 square feet.
An 8 foot long table is probably 30" wide. So, you'll need to cover 8 ft + 30 in + 30 in = 13 linear feet. To allow for the gathering you will want to double the length (26 feet) or approximately 9 yards.
