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.

Answer:

Therefore,

v=9\ meter

Step-by-step explanation:

Given:

GF = 12

GE = 16

DF = 12

CF = v

To Find:

v = ?

Solution:

In  Δ GFC and Δ GED

∠ E ≅  ∠ F …………..{ measure of each angle is 90° given }

∠ G ≅ ∠ G    ……….....{Reflexive Property}      

Δ GFC ~ Δ GED ….{Angle-Angle Similarity test}

If two triangles are similar then their sides are in proportion.

\frac{GF}{GE} =\frac{FC}{ED} =\frac{GC}{GD}\ \textrm{corresponding sides of similar triangles are in proportion}\\  

On substituting the given values we get

\frac{12}{16} =\frac{v}{12}\\\\v=\frac{144}{16}=9\\\\\therefore v=9\ meter

Therefore,

v=9\ meter

On Friday night, John ate pizza for dinner and had 1/2 of the pizza left over. On Saturday, he ate 1/3 of what was left. How muc
bixtya [17]
If john ate 1/2 on Friday, then there was a full half of pizza left when he finished.
And if he ate 1/3 of what was left on Saturday, there was only 2/3 of the pizza left for him to eat. So he ate 2/3 of a pizza on Sunday
