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.

Answer:
about 145.3 mg
Step-by-step explanation:
If half breaks down in the hour, then half remains. That is, each hour the amount remaining is multiplied by 1/2. The remainder after 6 hours is ...
(9300 mg)(1/2)^6 = 145.3125 gm
About 145.3 mg will be left after 6 hours.
