answer in terms of

Answers

Step-by-step explanation:

Given

Area of a circle (A) = 641 ft²

Circumference (C) = ?

We know

πr² = 641

r² = 641 / 3.142

r² = 204

r = 14.28 ft

Now

Circumference

= 2πr

= 2 * 3.14 * 14.28

= 89.68 ft

Hope it will help :)

What is distance formula?

The distance formula is a mathematical formula that is used to compute the distance between two points in a coordinate plane.

This formula is derived from the Pythagorean theorem, which states that the square of the length of the hypotenuse in a right triangle equals the sum of the squares of the lengths of the other two sides.

We can use the distance formula to find the length of AB:

[tex]d = \sqrt{ ((x2 - x1)^2 + (y2 - y1)^2)}[/tex]

Where (x1, y1) = (-4, 1) and (x2, y2) = (3, -1)

d = sqrt([tex](3 - (-4))^2 + (-1 - 1)^2[/tex])

= sqrt([tex]7^2 + (-2)^2[/tex])

= sqrt(49 + 4)

= sqrt(53)

≈ 7.3 (rounded to one decimal place)

Therefore, the length of AB is approximately 7.3 units.
