From the equation we see that the center of the circle is at (-2,3) and the radius is 9.
So using the distance formula we can see if the distance from the center to the point (8,4) is 9 units from the center of the circle...
d^2=(8--2)^2+(4-3)^2 and d^2=r^2=81 so
81=10^2+1^2
81=101 which is not true...
So the point (8,4) is √101≈10.05 units away from the center, which is greater than the radius of the circle.
Thus the point lies outside or on the exterior of the circle...

Answer:
The circumference is 18.84 inches.
Step-by-step explanation:
To find the circumference of the circle we can use the formula:
Where C is circumference and r is radius.
Now that we have the formula, we can substitute the numbers:
Answer:
x=5 1/4
Step-by-step explanation:
2 1/4= 
---> divided by 3 to find 1/7x----> 
=1/7x---> x=21/4---> x=5 1/4
All sides are equal on a triangle
Answer:
22
Step-by-step explanation:
22 x 2 is 44 plus 100 is 144
