Answer:
(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 = <u>7</u>, 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.
The widths and depths are the same. Since volume is length x width x height, you get 2x2x4=16, 3x3x6=54, 4x4x8=128, 5x5x10=250
Answer:
0
Step-by-step explanation:
The domain is the x, you cant find x just from having y, so i guess your x=0
Out of numbers: 5, 7, 21, 25, 28, 35, 42, 56, 75, and 80, choose those which are multiples of 4 or 7
