Radius, Diameter and Circumference
The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle.
Will if your trying to simplify each side then it is all ready but if your trying to combine each one then here is how to
-2.9a+6.8=4.4a-7.3
+2.9a +2.9a
6.8=7.3a-7.3
+7.3 +7.3
14.1=7.3a
dvide each side by 7.3
1.93=a
