Answer:
The line segment 7 cm long is shown below.
Step-by-step explanation:
First we draw a line line segment whose length is 7 cm long. Then we divide the line in small parts.
The length of each part is 1 cm.
Six points on the line segment divides the line in 7 equal parts and length of each part is 1 cm.
From the figure it is noticed that we have total 7 small parts and length of each part is 1 cm. So length of 7 parts is

Hence the total length of line is 7 cm.
Answer:
63753.8888
Step-by-step explanation:
2.0² * π = 12.56637...
12.56637... * 9.6 = 120.6371579...
120.6371579.. / π = 38.4
√38.4 = 6.196773354... --> the radius of circle A dialated by 9.6 = 6.2 cm
