Question

The center circle on a playing field has a radius of 7.5m find its circumference

Answer 1

Given:

• r= 7.5 m

Note that:

• r= radius

To find:

The circumference of the circular playing field.

Solution:

`\huge\boxed{Formula:C= 2\pi{r}}`

We'll have to multiply 2, π and radius.

Substitute the values according to the formula.

`C= 2× \pi ×7.5`

`C= 47.12389`

`\large\boxed{C= 47.12 \: m}`

Therefore, the circumference of the circular playing field is 47.12 feets.
