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
Point 1 (0, - 2)
Point 2 (8,0)
Slope = (y2-y1)/(x2-x1)= (0-(-2))/(8-0)=2/8=1/4
y-intercept (from the Point 1 (0, - 2)) is -2.
Equation : y=(1/4)x - 2
Coordinates to test are (4,-1).
y=(1/4)x - 2
-1=(1/4)*4 -2
-1=1-2
-1=-1 True
Answer:
23
Step-by-step explanation:
a pair is 2 so 2 pairs time 3 2x3=6 so 17+6=23
