The measures of two consecutive angles in a parallelogram are in the ratio 4: 8. what are the measures of the four angles of the parallelogram?

120,120,60,60

Step-by-step explanation:

I believe your answer is:

C. Two times r equals the diameter of the circle. Pi is needed for all circle formulas, so you multiply by Pi since you are finding the circumference.

2r = d    or, 2 radius = one diameter

π is used in both circle equations:

2πr (circumference)
πr² (area of circle)

hope this helps
