What is the approximate distance around the half circle with radius 12 centimeters?

1 answer:

4 0

You can find the perimeter of a circle by using the radius.
circumference = 2 $\pi r$
Circumference = 2 $\pi x 12$
circumference = 24 pi
Since you are only trying to find half of the circle you would divide your answer by 2

24pi / 2 = 12 pi

12 pi = 37.68

The answer is B. 37.7

Answer:

$x = \pm 2\sqrt3$

Step-by-step explanation:

Hello!

Let's use the square root property to solve this question

Solve:

$x^2 = 12$
$\sqrt{x^2} = \sqrt{12}$
$x = \pm\sqrt{12}$
$x = \pm \sqrt{4 * 3}$
$x = \pm 2\sqrt3$

The answer is option A: x = ±2√3

I am too lazy I'll explain so you find 688 minus 267 then you divide the difference by 6 and then u subtract the difference from 267x100 because that will be the total. Then u find the mean of the 94 numbers u get!
