Answer:

7

Step-by-step explanation:

Triangle Proportionality Theorem : If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.

\frac{RP}{PT} = \frac{SQ}{QT}     Set up proportions

\frac{6}{18} = \frac{x}{21}        Cross multiply

18x = 126   Divide to isolate x

x = 7

C = 3.14 × d

C = 3.14 × (34)

C = 106.76 cm

The circumference is around 106.76 cm
