Answer:
11cm = diameter.
c=circumference
d=diameter
π=3.14
r=half of diameter
34.56
C=2πr
d=2r
Solving for d (diameter)
d=C
π=34.56
π≈11.00079cm
rounded = 11cm!

Answer: n = 130
Step-by-step explanation:
 The sequence is an Arithmetic progression ( AP )
The last term of the sequence is (L) is 394 with the formula
 L  = a + ( n- 1 )d . From the sequence, a = 7, d ( common difference ) = 3 and L ( last term ) = 394, and n = ?
Put those values in the formula above and solve for n.
   a + ( n - 1 )d =  L
   7 + ( n - 1 ) x 3  = 394
          7 + 3n - 3   = 394
              4 + 3n     = 394
                     3n     = 394 - 4
                      3n     = 390
                         n     = 130
