Find the circumference of a circle with an area of 113.1 in square

Step-by-step explanation:

In order for us to find the circumference, we need to find the radius from the given area by rearranging the area formula.

Now that we have the radius, we can find the circumference.

So, when given 113.1 in sq for the area, the circumference of the circle is 37.68 in.

the answer is b

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
