Answer:

9.115 cm.

Step-by-step explanation:

\text{If the radius of the circle is represented by r,}\\\\\text{Circumference of circle = } 2 \pi r\\\\\text{But, given circumference = 57.2 cm}\\\\\text{Thus, according to question,}\\\\2 \pi r = 573 \div 10\\\\\implies 2 \times \dfrac{22}{7} \times r = \dfrac{573}{10}\\\\\\\implies r = \dfrac{573 \times 7}{2 \times 22 \times 10} = 9.115 \: cm

Hope it helps.
