Answer:
[tex]Distance\ cover\ by\ Rosa = 141.3\ m[/tex]
Step-by-step explanation:
Given:
Rosa has to skate around a face off circle five times.
[tex]Distance = 5\times circumfrance\ of\ circle[/tex]
Diameter of a circle = 9.0 m
Radius of a circle = [tex]\frac{d}{2} =\frac{9}{2}=4.5\ m[/tex]
Solution:
We know that the circumference of a circle.
[tex]C = 2\pi r[/tex]
Where;
r = Radius of a circle
Substitute [tex]\pi =3.14\ and\ r = 4.5[/tex] in above equation.
[tex]C = 2\times 3.14\times 4.5[/tex]
[tex]C = 28.26\ m[/tex]
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.
[tex]Distance\ cover\ by\ Rosa = 5\times 28.26[/tex]
[tex]Distance\ cover\ by\ Rosa = 141.3\ m[/tex]
Therefore, the distance cover by Rosa to skate 141.3 m.
