WILL GIVE BRAINLIEST FOR ANSWER Find the area of the shaded polygons.
trapecia [35]

Answer:

7.74 cm2

Step-by-step explanation:

We need to find the area of both the square and the circle and then subtract the two.  Inscribed means draw within a figure so as to touch in as many places as possible.  So the circle is drawn inside the square.  The opposite is circumscribed, meaning drawn outside.

Asquare = s2 = 36 cm2 so the side is 6 cm

6 cm is also the diameter of the circle and thus the radius is 3 cm

A circle = πr2 = 3.14 * 32 = 28.28 cm2

The resulting difference is 7.74 cm2

Alsion saves $29.26 each month. How many months will it take her to save enough money to buy a stereo for $339.12?
Darya [45]

Answer: 12 months (1 year)

We know that Alision gains $29.26 each month. She wants to buy a stereo for $339.12

You want to divide $339.12 with $29.26 to find the total months.

339.12 / 29.26 = 11.6

CHECK:

You want to round up, since she needs the money to buy a stereo. She's allowed to have more money.

29.26 * 12 = 351.12

It will take Alision 12 months (1 year) to buy her stereo.
