Answer:
Radius is <u>2.8</u> Circumference is <u>17.584 or 17.6 Rounded to the nearest Tenths </u>
Step-by-step explanation:
1. Find circumference with the Formula <u>C=πd</u>
C=3.14 x 5.6
<u><em>C=17.584 or 17.6 Rounded to the nearest Tenths </em></u>
2. Radius is Always half of the Diameter.
5.6/2 = 2.8
<em><u>2.8 is your radius.</u></em>
3. If you want to check you work try the formula C=2πr to see if things checks out.
C=2 x 3.14 x 2.8
<u><em>C= 17.584 or 17.6 Rounded to the nearest Tenths </em></u>

<u><em>Hope this Helps!</em></u>
Conversion Formula: Radian/π = Degree°/180°
R= 7π/4, Degree =?
Apply the formula:
So [(7π/4) / π = Degree / 180] (note that 7π/4) / π = 7/4)
Degree = (7/4) x 180° = 315°
