The area of a sector of a circles is calculated by the equation A = πr^2 (theta/360). From the data of the sector, we determine the radius of the circle. THen, we can calculate for the area of the circle.
16.4π = πr^2 (72/360)
r = 9.06
Area of circle = πr^2
Area of circle = π(9.06)^2
Area of circle = 82π

(1) Snow fall in last week = inches
Snow fall in today= inches
Let us first change mixed fraction to improper fraction.
Now, make the denominators same.
,
Now, find the difference between 14/4 and 23/4.
So, compared to last week more inches of snow fell today.
(2) Given three times a number, minus nine, equals six times six, divided by four.
Let a number be X.
3X – 9 = 6 × 6/4
(3) To solve the equation:
3X – 9 = 6 × 6/4
3X – 9 = 36/4
3X – 9 = 9
3X = 18
X = 6
5.2 cup is the same as 65% of what number
Now let's put that into math:
5.2 = 65% of n
5.2 = .65n
Divide both sides by .65 to get n by itself
<u>5.2</u> = <u>.65</u> n
.65 .65
n= 8 cups in this batch of salsa
Notice that dividing by .65 (a number less than 1) made the 5.2 actually increase to 8. Division does not always make thing smaller.
