Answer:
We use formula, circumference= [tex]2\pi r[/tex] to get r= 7.48
Step-by-step explanation:
Here is the complete question: The circumference of a pool is 47 feet. Which formula can you use to find Radius (r), if you know that C =2πr.
Given: Circumference= 47 feet.
We will use formula of circumference to find radius (r) as given.
Circumference = [tex]2\pi r[/tex]
⇒ [tex]47\ feet= 2\times 3.14\times r[/tex] (∵ we know π=3.14)
Cross multiplying both side to get r.
⇒ r= [tex]\frac{37}{2\times 3.14} = 7.48[/tex]
∴ radius (r)= 7.48
∴ We will use circumference formula [tex]2\pi r[/tex] to find Radius (r).
