Answers
Step-by-step explanation:
Given:
\textsf{Circumference of the circle is}Circumference of the circle is
\mathsf{\dfrac{75}{2}\;cm}

Solution:
\mathsf{Formula\;used:}Formulaused:
\boxed{\mathsf{Cirmcumference\;of\;a\;circle\;of\;radius\;r\;is\;2\,\pi\,r\;units}}
Cirmcumferenceofacircleofradiusris2πrunits
\textsf{Let r be the radius of the given circle}Let r be the radius of the given circle
\textsf{Circumference of the circle}\mathsf{=\dfrac{75}{2}\;cm}Circumference of the circle=
2
75
cm
\implies\mathsf{2\,\pi\,r=\dfrac{75}{2}}⟹2πr=
2
75
\implies\mathsf{2{\times}\dfrac{22}{7}{\times}r=\dfrac{75}{2}}⟹2×
7
22
×r=
2
75
\implies\mathsf{r=\dfrac{75{\times}7}{2{\times}44}}⟹r=
2×44
75×7
\implies\mathsf{r=\dfrac{525}{88}}⟹r=
88
525
\implies\boxed{\mathsf{r=5.97\;cm}}⟹
r=5.97cm
