Answer:
88
Step-by-step explanation:
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
To complete the square, you can add (and subtract) the square of half the x coefficient.
... y = x² -10x + 30
... y = (x² -10x +25) + (30 -25)
... y = (x -5)² +5
The equation is not setup properly, possibly it is your teacher's fault.
From external research, I would say the answer is x = -12.
