A=pi times r2 so you would do 3.14 times 8.6 ^2 and your answer would be 232.35
Answer:
b
Step-by-step explanation:
The formula for a circle is (x-h)^2 + (y-k)^2 = r^2 where h is x-value and k is the y-value of the center.
If diameter is 24, the radius is 12
(x + 9)^2 + (y - 5)^2 = 144
Solution :
Given that the area model that represents a quotient of 108 ÷ 9.
So, we multiply 9 by multiples of
to 
10 20 30 40
90 180 270 360
Because 108 is between 90 and 180, the quotient lies between 10 and 20.
Using 10 as the first partial quotient in the area model for 108 ÷ 9,
9 x 10 = 90 , so 108 - 90 = 18
Now, 9 x 2 = 18, so 18 - 18 = 0
∴ 10 + 2 = 12
Therefore, the quotient of 108 ÷ 9 is 12.
If you wrote this in point-slope form, it’ll be y+8=-6(x-2).
This equation written in slope intercept form would be y = -6x+4.
He messed up because he was supposed to change the double negative into a positive then solve. He was not supposed to add 8 on both sides.
So, the answer is y = -6x+4.
Hope this helps!
