<u><em>The complete question is</em></u>
A circle with a radius of 3 cm sits inside of a circle with a radius of 5 cm. What is the area of the Shaded Region?
The shaded region is the area outside the smaller circle and inside the larger circle
we know that
The area of the shaded region is equal to subtract the area of the smaller circle from the area of the larger circle
Remember that
The area of the circle is equal to
so
The area of the shaded region is

Answer:
A. $3.63
Step-by-step explanation:
You can choose the correct answer simply by estimating.
The almonds are about $5.50 for each of the 2 kg, so will total about $11. Since the total amount paid is just over $25, the amount paid for cashews is about $25 -11 = $14.
That amount pays for 4 kg of cashews, so 1 kg will be half of half that amount, or about $3.50 -- certainly, less than $7.26.
_____
If you want to write an equation, you can write ...
2(5.49) +4(c) = 25.50
4c = 14.52 . . . . . . . . . . . . subtract 10.98
14.52/4 = c = 3.63 . . . . . divide by the coefficient of c
1 kg of cashews has a price of $3.63.
