Sagot :

Answer:

1130.97 ft (nearest hundredth)

Step-by-step explanation:

Circumference of a circle = 2[tex]\pi[/tex]r,  where r = radius

Given radius = 30 ft

⇒ circumference = 2 x [tex]\pi[/tex] x 30 = 60[tex]\pi[/tex] ft

If the skater does 6 laps of the rink:

⇒ 6 x 60[tex]\pi[/tex] = 360[tex]\pi[/tex] = 1130.97 ft (nearest hundredth)
