Is the point (-3 , 5) inside, outside or on the circle with equation (x+2)² + (y-4)² = 9?

• Inside the Circle
• Outside the Circle
• On the Circle

For what value of K is the point (1 , K) inside the circle with equation x² + y² = 4?

• K = 1
• K = 2
• K = 3
• K = 4

For what value of K is the point (K , -2) outside the circle with equation:
x² + y² = 9?

• K = 1
• K = 2
• K = 3
• K = -1

For what value of K is the point (K , 2K) on the circle with equation x² + y² = 5?

• K = √5
• K = -1
• K = 2
• K = 0

How do you determine if a point is inside the circle?

• See if value after substitution for (x, y) = r²
• See if value after substitution for (x, y) > r²
• See if value after substitution for (x, y) < r²

How do you determine if a point is outside the circle?

• See if value after substitution for (x, y) = r²
• See if value after substitution for (x, y) > r²
• See if value after substitution for (x, y) < r²

How do you determine if a point is on the circle?

• See if value after substitution for (x, y) = r²
• See if value after substitution for (x, y) > r²
• See if value after substitution for (x, y) < r²
