Question

For hockey practice, Rosa has to skate around a face off circle five times. The face off circle has a diameter of 9.0m. About how far does Rosa have to skate?

Answer 1

`Distance\ cover\ by\ Rosa = 141.3\ m`

Explanation:

Given:

Rosa has to skate around a face off circle five times.

`Distance = 5* circumfrance\ of\ circle`

Diameter of a circle = 9.0 m

Radius of a circle =
`(d)/(2) =(9)/(2)=4.5\ m`

Solution:

We know that the circumference of a circle.

`C = 2\pi r`

Where;

r = Radius of a circle

Substitute
`\pi =3.14\ and\ r = 4.5` in above equation.

`C = 2* 3.14* 4.5`

`C = 28.26\ m`

So, the circumference of the circle is 28.26 m.

Rosa has to skate around a face off circle five times, so Rosa cover 28.26 m 5 times.

`Distance\ cover\ by\ Rosa = 5* 28.26`

`Distance\ cover\ by\ Rosa = 141.3\ m`

Therefore, the distance cover by Rosa to skate 141.3 m.
