\textbf{Solution:}Solution:
\text{Let r be the radius of the given circle}Let r be the radius of the given circle
\text{Since circumferemce of the circle is 62.8 m, we have}Since circumferemce of the circle is 62.8 m, we have
2\,\pi\,r=62.82πr=62.8
2{\times}3.14{\times}r=62.82×3.14×r=62.8
6.28\,r=62.86.28r=62.8
\implies\,r=\dfrac{62.8}{6.28}⟹r=
6.28
62.8
\implies\boxed{\bf\,r=10\,m}⟹
r=10m

Identify the difference of circumference of two concentric circles whose width is 3.5 CM.
A. 22cm
B. 20cm
C. 24cm
D. 26cm
Answer :
Circumference = 2 π r
62.8 = 2 × 3.14 × r
62.8 = 6.28 × r
r = 62.8/6.28
r = 10 cm
The radius of the circle is 10 cm.
