Answer:The area of a circle is pi times the radius squared (A = π r²)
Step-by-step explanation:The area of a circle is pi times the radius squared (A = π r²)
No. when the line reaches 4 on the x axis it is at 13 on the y axis.
The line is going downwards
Solution: negative slope
Answer:
96 square inches.
Step-by-step explanation:
From given picture we see that
BC=8 in
AD=10 in
Given that
AD=AB
Then AB=10 in
Apply Pythagorean theorem in triangle ABC to find AC






take square root

Then area of triangle ABC 

There are total 4 congruent triangles.
Then total area of the given figure = 4(24)=96 square inches.
Answer: 
Step-by-step explanation:
The standard form of a circle is written as such:

Where (h, k) is the center of the circle, and r is the radius.
We know that the center is (-7, 0), so we can plug that into the equation like this: 
The radius is 3 * the square root of 3. To square this, we can multiply 3 squared and the square root of 3 squared:

So, your standard form equation is the following:
