Question

Find the circumference of a circle if the radius is 15 ft. Use 3.14 for pi.

Answer 1

`\huge{ \boxed{ \sf{94.2 \: ft}}}`

Explanation:

`\underline{ \sf{Given}} :`

`\star{ \sf{ \: Radius \: of \: a \: circle \: ( \: r \: ) \: = \: 15 \: ft}}`

`\star{ \sf{ \: pi \: (\pi) = 3.14}}`

`\boxed{ \sf{ \: Circumference \: of \: a \: circle \: = \: 2 \: \pi \: r}}`

Plug the values and multiply them

`\mapsto{ \sf{Circumference = \: 2 \:* \: 3.14 \: * \: 15}}`

`\mapsto{ \sf{Circumference \: = \: 94.2 \: ft}}`

Hope I helped!

Best regards! :D

Answer 2

Circumference = 2 x radius x Pi

Circumference = 2 x 15 x 3.14

Circumference = 30 x 3.14

Circumference = 94.2 feet
