Eight with the decimal numbers of eight hundred twenty-five.

Original Circle Area = 45
A = pi * r^2
Plug in what we know:
45 = 3.14 * r^2
Divide 3.14 to both sides:
14.3312102 = r^2
Find the square root of both sides:
r = 3.78565849
Find 2/3 of this:
2/3 * 3.78565849 = 2.52377233
So this is the radius of the newly dilated circle.
A = pi * r^2
A = 3.14 * 2.52377233^2
A = 3.14 * 6.36942677
A = 20
So the area of the newly dilated circle is 20 square inches.
Total students = 24
students earning an A= 14
Probability = 14/24 = 7/12
4(x+7)=38
4x + 28 = 38 - distribute the 4 into x and 7
4x = 10 - subtract 28 from both sides
x = 2.5 - divide both sides by 4 to get x by itself
answer - x = 2.5
