(i) The surface(sheet) of a conical tent is circular so we must use the formula for the area of a circle to find out;

Given the diameter 14, we must find the radius.

To find the radius we must do 1/2 of the diameter to get the radius.

14 x 1/2 = 7, is the radius

Formula for area of a circle;

a = πr^2

where pi is 3.14 or 22/7, r is the radius which is being squared

Plug in the actual values:

a = πr^2

a = 3.14 x 7^2

a = 3.14 x 49

a = 153.86 square meters, is the area of the conical tent's sheet.

(ii) Since there are 153.86 meters in one sheet, we should multiply that by         $12(because $12 per meter) to get the total cost.

So,

153.86 meters x $12 = $1,846.32, it would cost 1,846.32 dollars.
