Answer:
A) 78
Step-by-step explanation:
The given sequence is an arithmetic sequence.
Here A1 = -6, common difference = (3/2)
nth term An = a1 + (n -1)d
A57 = -6 + (57 -1)3/2
= -6 + (56)*3/2
= -6 + 28*3
= -6 + 84
A57 = 78
Thank you.
Answer:

Step-by-step explanation:
Answer:
10.05 meters
Step-by-step explanation:
If the diameter is 3.2 meters, then the radius is 1.6 meters.
Use the circumference formula, C = 2
r, and solve for C
C = 2r
C = 2(1.6)
C = 3.2
C = 10.05
So, to the nearest hundredth of a meter, the circumference is 10.05 meters
