Step-by-step explanation:
To find the Circumference of a triangle you use the formula C= 2(pi)r
in both of the problems you have the radius(r) and you plug the #'s in and solve
(pi)= 3.14...
#1.
2(pi)14.5
28(pi)
C= 87.92
#2.
2(pi)9.5
19(pi)
C= 56.66
8 is the total number of markers in the bag. There are 3 out of 8 that are red. 8-3=5 so there are 5 out of 8 markers that are not red and that are other colors - or 5/8 are other colors.
5+3a = 3-2a
So
5a = -2
a=-2/5=-0.4
