Answer:
About 316.13
Step-by-step explanation:
We know:
Diameter (d) = <u>11</u> (of the circle)
Area of the circle: pi(11)^2 = <u>121pi </u>
Side of the square = <u>8 </u>
so area of the square is 8^2 = <u>64</u>
Area of the shaded region:
121pi-64 =316.13
hope this helped

It took 32.4 minutes for the battery to be fully charged.
Step-by-step explanation:
The answer is <span>The liquid must be in the cooler fewer than 10 minutes.
</span>
Let:
m - the number of minutes the liquid is in the cooler.
a - the starting temperature
The function is:
f(m) = a - 3 * m (Since the temperature decreases by 3°F each minute m, it has a negative sign)
Let:
m - <span>the number of minutes the liquid is in the cooler.
a - the starting temperature
</span>a = 90<span>°F
</span>
<span>The temperature of a liquid must stay above 60°F:
f(m) > 60
Thus:
</span>f(m) = a - 3 * m
f(m) > 60
a - 3 * m > 60
90 - 3m > 60
90 - 60 > 3m
30 > 3 m
30/3 > m
10 > m
Or m < 10. So the correct answer is The liquid must be in the cooler fewer than 10 minutes.
