Answer:
≈ 153.86
Step-by-step explanation:
Area of a circle's formula is: A = πr² π in this would be approximately 3.14
using this formula and the given radius, we can plug it into the formula
A = (3.14)(7)² --> A= (3.14)(49) ≈ 153.86
Answer:
1/3= 5/15
Step-by-step explanation:
Answer:
-10, 3
Step-by-step explanation:
-10, 3 work since
-10 + 3 = -7
N is a placeholder for a number. In this case, it is 4
We will replace every copy of 'n' with '4' and then simplify
So n+8 turns into 4+8 which simplifies to 12
Is 12 less than or equal to 13? Yes it is. Specifically it is less than 13. So n = 4 is part of the solution set.
Here is how you'd write it all out using algebra



The last inequality is true so the first inequality is true when n = 4. This is another way to see that n = 4 is a solution.
