The area of a circle, given the circumference, is found using this formula:
A = C²/4π
Therefore,
A ≈ 451.93 cm²
Answer:
16
Step-by-step explanation:
x = number of footballs he can order
22*x + 13 (shipping fee) = 277
22x = 264 Subtract 13 from both sides
x = 16 Divide both sides by 22
Our solution is 16 footballs
Answer:

Step-by-step explanation:
<u>Given the following data;</u>
Length = 312 meters
Breadth = 186 meters
To find the perimeter of the rectangle;
Mathematically, the perimeter of a rectangle is given by the formula;
Perimeter = 2(L + W)
Perimeter = 2(312 + 186)
Perimeter = 2(498)
Perimeter = 996 meters
To the nearest meters, we have;
Perimeter = 996 ≈ 1000 meters
Let P represent the perimeter of a rectangular field.
900 < P > 1000
Therefore, 
I think it is 14 if my calculations are correct.
Hope it helps
