</span><span>The formula for calculating the area of a circle is;
Area = πr^2
Where π = 3.142
r = radius of the circle.
When a sector of the circle is involve area is a fraction of the whole circle and it is given by;
Area of a sector = θ/360 πr^2
Where ϴ = angle that makes the sector
So, area = 120/360 π9^2=</span>27π

Answer:
27.5
Step-by-step explanation:
first you find what 30x30 is as A squared plus B squared is equal to C squared. your A is 12 and your C is 30.
so!
30x30 is 900
12x12 is 144
subtract 144 from 900 and you get 756. once you find the square root you get 27.49. then round up to 27.5
28,33,38,43
the common difference can be found by subtracting the first term from the second term.....33 - 28 = 5....so the common difference (d) = 5
an = a1 + (n - 1) * d
n = the term u want to find = 11
a1 = first term = 28
d = common difference = 5
now we sub
a11 = 28 + (11 - 1) * 5
a11 = 28 + 10 * 5
a11 = 28 + 50
a11 = 78
Answer: (0,1)
Step-by-step explanation:
The initial value is simply the starting value of the graph, so it is where the graph starts
Hello! For this question, we are compounding. The formula for compounding is P(1 + r)^t, where P = initial amount, r = rate, and t = time in years. In this problem, the rate is 1.2%. 1.2% is 0.012 in decimal form. Let's add 1 to that. 1 + 0.012 is 1.012. That part is done. Next, we raise it to the 7th power, because 2008 to 2015 is 7 years apart. 1.012^7 is 1.08708521101. This is a long decimal, but do not delete it from your calculator. Now, we multiply that number by 6.68 billion, which is 6,680,000,000 in standard form. When you do that, you get 7,261,729,209.52 or 7,261,729,210 when rounded to the nearest whole number. There. The world population will be 7,261,729,210 by 2015.
