what is the circumference of the circle? use 22/7 for pi

44 cm
55 cm
100 cm
110 cm

circumference of the circle is d=35/2cm

For this case we have that by definition, the circumference of a circle is given by:

Where:

d: It is the diameter of the circle

They tell us that:

Substituting:

Thus, the circumference of the circle is 55 centimeters.

Option B

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°.
