Question

There will be a circular patio with a diameter of 7 metres. Greg is going to put a tiled edge around the patio. What is the circumference of the patio? m Circumference of a circle = 2πr Use π = 3.14

Answer 1

`\boxed{21.98 \: \mathrm{meters}}`

Explanation:

Apply formula for circumference of a circle.

`C=\pi d`

`d:diameter`

Take
`\pi =3.14`

Plug
`d=7`

`C=3.14 * 7`

`C= 21.98`

Answer 2

`Circumference = 21.99 \ m`

Explanation:

Circumference =
`\pi d`

Given that d = 7 m

`Circumference = (3.14)(7)\\`

`Circumference = 21.99 \ m`
