A circle with a radius of 15.4 meters.

Which statements are true about the circle shown? Check all that apply.

The diameter of the circle is 30.8 m.

The circumference in terms of Pi is 30.8Pi m.

The circumference of the circle can be found using 2(Pi)(15.4)

The approximate circumference of the circle rounded to the nearest tenth is 96.7 m.

A little more than 6 diameters could be wrapped around the circle.

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

phosphate, calcium ion, chloride ion, neon atom

step-by-step explanation:

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
