Answer:
37.68cm
Step-by-step explanation:
C = 2  r
 r
C	=	circumference
 =	the constant pi (3.14)
 =	the constant pi (3.14)
r	=	radius of the circle (6cm)
d      =      diameter of the circle (12cm)
d = 2r
C = 2 · 3.14 · 6
C = 37.68cm

The fifth term is 620
Step-by-step explanation:
y=40×(-2)^(n-1)
The 5th terms means n=5
y = 40 * (-2) ^ (5-1)
   = 40 * (-2) ^4
   = 40 * (16)
   = 640
