The formula of an area of a circle:

r - a radius
We have r = 14m. Substitute:

If you want an approximate area, you can accept 
Then:

The angle the radius makes with AB is a right angle, so the Pythagorean theorem applies.
r² = 17.4² - 7² = 253.76
r = √253.76 ≈ 15.9
The length of radius r is about 15.9.
14 and 15
14^2 = 196
15^2 = 225
225+196 = 421
There was 125,933 fans that attended both games.
Answer: 16517 dollars
Step-by-step explanation:
Given that x is the number of years after 2000.
In 2005, the number of years x = 4
Because the equation was modelled for 4 year college courses
The best estimate for the average cost of tuition in 2005 will be
ŷ = 937.98(4) + 12,764.90
Y = 3751.92 + 12764.9
Y = 16516.82 dollars
Y = 16517 dollars
