Answer 1

`{ \bf{ \underbrace{Given :}}}`

Radius of the circle = 9 m.

`{ \bf{ \underbrace{To\:find:}}}`

The circumference of the circle.

`{ \bf{ \underbrace{Solution :}}}`

A. C = 18 π ✅

`\sf\orange{The\:circumference \:of\:the\:circle\:is\:18\:π\:m.}`

`\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\orange{:}}}}}`

We know that,

`\sf\purple{Circumference\:of\:a\:circle \:=\:2Πr }`

`= 2 \: \pi * 9 \: m \\ = 18 \: \pi \: m`

Therefore, the circumference of the circle is 18 π m.
