Answer 1

`\huge\bf\underline{\underline{\pink{A}\orange{N}\blue{S}\green{W}\red{E}\purple{R:-}}}`

Here we've been provided with the information given that radius (r) = 3.

And we have to find the circumference (c) of circle. And we have been provided with the formula i.e C = 2πr.

Placing (π = 3) in the above equation,

`:\implies\tt{c = 2\pi r}`

`:\implies\tt{c = 2 * 3 * 3}`

`:\implies\tt{c = 6 * 3}`

`:\implies\tt{c = 18}`

• The circumference of circle is 18cm.

Answer 2

C = 18

Explanation:

Put the numbers in place of their symbols and do the arithmetic. The diagram is showing you r = 3.

C = 2πr

C = 2(3)(3) . . . . . using 3 for π, as directed

C = 18
