Question

Find the circumference of a circle.

Answer 1

56.52

Explanation:

1. multiply your r by 2

so 9*2= 18

2. multiply that by pi, which you substitute 3.14 in for

so 18*3.14=56.52

Answer 2

`\large\blue{Given \: - }`

Radius ( r ) = 9 inches

`\blue{To \: find\:-}`

Circumference of the Circle ?

`\blue{Solution\:-}`

Circumference of the Circle = 2πr

Putting the value of r in the formula -

`= 2\pi r`

`= 2 * (22)/(7) * 9`

`= 56.5 \: inches`

`\mathsf \pink {Hence, \: the \: circumference \: of \: the \: circle \: is \: 56.5 \: in.}`
