Answer:
28.27cm²
Step-by-step explanation:
formula:
A=πr²
d = 2r
Solving for A
A=1/4π d² = 1/4 · π · 6² ≈ 28.27433cm²
rounded: 28.27cm²
hope this helped!
Answer:
48
Step-by-step explanation:

is basically the horizontal axis.
First, find the integral of x^2-25.
Remember that
integral of a constant is that constant times x.
Also that
to take the integral of a power function, add 1 to the degree and divide by that same degree.

We then get

Evaluate at -3


Then we evaluate at 0

Next, we subtract the the answer then we get

The formula of combination is

We have

and


Hence, there are 1001 ways of arranging 10 records from 14 records
Answer:

Step-by-step explanation:
1. Blue region. The boundary blue line passes through the points (0,-7) and (3,8), then its equation is

This line is solid, so the sign for the inequality should be with the notion "or equal to".
From the diagram you can see that the origin belongs to the blue region, then its coordinates satisfy the inequality. Thus,

2. Green region. The boundary green line passes through the points (6,-1) and (0,3), then its equation is

This line is solid, so the sign for the inequality also should be with the notion "or equal to".
From the diagram you can see that the origin doesn't belong to the blue region, then its coordinates satisfy the inequality. Thus,

3. The system of linear inequalities that represents these graphs is
