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

Answer:

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

Step-by-step explanation:

Given:

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

$Distance = 5\times circumfrance\ of\ circle$

Diameter of a circle = 9.0 m

Radius of a circle = $\frac{d}{2} =\frac{9}{2}=4.5\ m$

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.

$C = 2\times 3.14\times 4.5$

$C = 28.26\ m$

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.

$Distance\ cover\ by\ Rosa = 5\times 28.26$

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

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