Answer:
86 cm²
Step-by-step explanation:
<u>1) Calculate the area of the square</u>
Therefore, the area of the square is 400 cm².
<u>2) Calculate the area of the circle</u>
we can substitute with 3.14. To find the radius, we divide the diameter of the circle by 2. 20 cm is the diameter of the circle, so therefore, its radius is 10 cm.
Therefore, the area of the circle is 314 cm².
<u>3) Subtract the area of the circle from the area of the square</u>
Therefore, the area of the shaded region is 86 cm².
I hope this helps!

Believe in yourself you can do it
Answer:
Part A: after 9 days the radius of the algae would be 12.81mm so the domain is 9. you would plot the domain at (0,9)
Part B: the y-intercept (the 9) represents the amount of algae the experiment started off with.
Part C: the rate of change is 0.
Step-by-step explanation:
<h3>1 SongBook costs =$25.85</h3><h3>A guitar costs =$250.10, so 2 Songbooks would cost 2*25.85=51.7.</h3><h3>(2 Songbook) $51.7 * (Guitar) $250.10 = $301.80</h3>
