The formula for an area of a circle is pi•r^2.
The diameter is 16, so the radius (half of the diameter) is 8. plug that into the formula and you get 64pi, or roughly 200.96
Answer: 30
Step-by-step explanation: when you look at the x value of 9, the y value on the best fit line would be 30
Answer : The value of x is 5.
Step-by-step explanation :
According to the angle bisector theorem, an angle bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of the triangle.
That means,


By the cross multiplication, we get:






Therefore, the value of x is 5.
