The formula given to us relates circumference with radius but we are given diameter instead. good thing we know that diameter is twice the length of radius so if diameter=28, the radius=14. therefore, using our formula, we can find the circumference:
C = 2(pi)(14)
C = 87.96
and this answer is close to 88 so the answer is A

<em>The number of isosceles triangle in the grid is: </em>
<em />
The dimension of the grid is given as:

Calculate the area


The area of each isosceles triangle is given as:

The number (n) of the triangle in an x-by-x grid is:

So, we have:

Express as products


Hence, the number of isosceles triangle in the grid is:

Answer:
7x + 14y + 2
Step-by-step explanation:
(3x+8y+8)+(4x+6y-6)
3x + 8y + 8 + 4x + 6y - 6
3x + 4x + 8y + 6y + 8 - 6
7x + 14y + 2

The correct ans is: 
Entry Fee for the player is $11.
Player is charged $1 for each game played. So for x games played, the charges will be $ x.
So, total charges for x games played will be:
T(x) = 11 + x
Average Cost per game played = Total Cost/Total Games played
So,
