Question

The circumference of a circle is 260.62 feet. What is the radius of the circle? Use 3.14 for π.

Answer 1

Given:-

• 
  `\rm{Circumference \: of \: a \: circle = \bold{260.62}}`

`\:`

• 
  `\rm{ {π ( pi ) = \bold{3.14}}}`

`\:`

To find:-

• 
  `\rm{radius= ?}`

`\:`

By using formula:-

• 
  `\boxed{ \rm{Circumference \: of \: circle \: = \bold{2πr}}}`

`\:`

Solution:-

• 
  `\rm{C = 2 π r}`

`\:`

• 
  `\rm{260.62 = 2 × 3.14 × r}`

`\:`

• 
  `\rm{260.62 = 6.28r}`

`\:`

• 
  `\rm{r = \cancel(260.62)/(6.28) }`

`\:`

• 
  `\underline{ \boxed{ \rm{ \red{ \: r = 41.5 \: }}}}`

`\:`

The radius of circle is 41.5.

hope it helps! :)
