Acircle's circumference is 600 m. what is a good approximation of the circle's area

Answer : The approximation of the circle's area is

Step-by-step explanation :

As we know that:

Circumference of circle =

Area of circle =

Given:

Circumference of circle = 600 m

First we have to calculate the radius of circle.

Now we have to determine the area of circle.

Area of circle =

Now put the value of 'r' in this formula, we get the area of circle.

Area of circle =

The value of

So,

Area of circle =

Area of circle =

Therefore, the approximation of the circle's area is

you are saying it as if a fact, not a question, but yes, you would be correct? ; )

step-by-step explanation:

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
