Answer:
254.4 in²
Step-by-step explanation:
Area of a circle is given by the formula:
Our radius is 9 so we substitute this into the equation:
π(9)² = 81π
81π = 254.4 in²
Answer: (y*40)+(y*8)
Step-by-step explanation:
Answer:1/3
Step-by-step explanation:
It’s 4/12 so divide both numbers by 4 is 1/3
<u>Answer</u>
Center: (1,-12)
Radius: 5
<u>Work</u>
+
-2x+24y+120=0 (Subtract 120 on both sides and rearrange)
-2x++24y=-120 (Then divide 2 by 2 and square it. Do the same for 24.)
-2x+1++24y+144=-120+1+144 (You have to add the same numbers on both sides)
(Simplify)
So you would put (1,-12); r=5
Well if you use graph paper you can graph the points you already have and then you can find the slope of the line easiest that way, the next point would be. (-1,8)
