(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.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
