DOG A dog is leashed to the corner of a house. How much running area does the dog have? Explain how you found your answer.
1 answer:
Answer:
The area will be where r is the length of the leash.
Step-by-step explanation:
The area of a circle is pi times the radius squared. One forth of that area is not available for the dog to run: its the corner of the house. so what's left is 3/4 of the area of the circle. (3/4)πr²
Since the length of the leash is not given in the question, no specific Area can be answered. Once that value is substituted for r, the actual area can be calculated.

Answer: C, E, F
Step-by-step explanation:
- Plug in the "x" and "y" values from the ordered pairs into the equation.
- For A: 3 =
→ 3 ≠ 1 → A is eliminated.
- For B: 5 =
→ 5 ≠
→ B is eliminated.
- For C: 2 =
→ 2 = 2 → C satisfies the equation.
- For D: 10 =
→ 10 ≠
→ D is eliminated.
- For E: -1 =
→ -1 = -1 → E satisfies the equation.
- For F: 3 =
→ 3 = 3 → F satisfies the equation.
- Therefore, C, E, and F are the answers.
