Answer 1

Answer:

iven:

\text{Circumference of a circle is 62.8 m}Circumference of a circle is 62.8 m

\textbf{To find:}To find:

\text{Radius of the circle}Radius of the circle

\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

\textbf{Answer:}Answer:

\textbf{Radius of the circle is 10 m}Radius of the circle is 10 m

Identify the difference of circumference of two concentric circles whose width is 3.5 CM.

A. 22cm

B. 20cm

C. 24cm

D. 26cm

Answer 2

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.
