Answer:
Is it A
Step-by-step explanation:
Area of circle, πr² = 452.16
πr² = 452.16
r² = 452.16/π, π ≈ 3.1416
r = √(452.16/π) = √(452.16/3.1416) ≈ 11.997
Circumference = 2πr
C = 2*3.1416*11.997
C ≈ 75.38
Circumference is ≈ 75.38 m.
Hope this helps.
Answer:
13.99p + 4.49s ≤ 80
Step-by-step explanation:
Pizza is p and soda is s. If he has only $80 to spend on a combination of both, he cannot obviously spend more than that. Therefore, the inequality sign is "less than or equal to". He can spend 80, but he can also spend less than 80. He cannot spend anything over that, since he doesn't have it to spend!
If pizzas are represented by p, and we know the cost of each one is 13.99, we represent one pizza as 13.99p; if the cost of sida is 4.49 per case, we represent one case as 4.49s.
The sum of these cannot exceed 80, so the inequality, then, is:
13.99p + 4.49s ≤ 80
