PLEASE HELP ASAP! A mountain climber is at an altitude of 2.9 mi above the earth’s surface.

shutvik [7]

You can use Pythagorean theorm to solve.

$a^2 + b^2 = c^2$
C = 3959 + 2.9 = 3961.9

x = ???? = a
b = 3959
Plugin our data.
$a^2 + b^2 = c^2$
$a^2 + 3959^2 = 3961.9^2$
$a^2 + 15673681 = 15696651.61$
$a^2 = 22970.61$
$\sqrt{a^2} = sqrt{22970.61}$
$a = 151.560$
$x = 151.560$
$x = 151.6$

The area of a circle is 9π in². What is the circumference, in inches? Express your answer in terms of \piπ

dangina [55]

Answer:

$6\pi$ in

Step-by-step explanation:

The formula to find the area of a circle: $\pi r^{2}$ , where $r$ is the radius.

The formula to find the circumference (perimeter) of a circle: $2\pi r$ , where $r$ is the radius.

1) To find the circumference of the circle, we need to find the radius ( $r$ ) first. Since the area of the circle is given to us, we need to equate this to the formula to find the area of a circle.

$9\pi =\pi r^2$

Cancel the $\pi$ by bringing it to the other side.

$9 =\pi r^2$ ÷ $\pi$

$9 = r^2\\\sqrt{9} = r\\3 = r$

2) Find the circumference of the circle by using the formula, $2\pi r$ .

= $2*\pi *3$

= $6\pi$ in
