Question

PLZ HELP ASAP RANDIans and arc length

Answer 1

The full arc of the circumference is:

S = 2pi * r

The arch is:

S '= (3/5) pi * r

Dividing we have:

S '/ S = ((3/5) pi * r) / (2pi * r)

Simplifying we have:

S '/ S = ((3/5)) / (2)

S '/ S = ((3/10))

Answer:

The fraction of the arch is:

S '/ S = ((3/10))

Answer 2

The complete circumfernce is 2pi
The fraction of the circumfrence is:
(3pi/5)/(2pi)=(3pi/5)/(2pi/1)=(3pi*1)/(5*2pi)=(3pi)/(10pi)=3/10

Answer: 3/10 of the circumference
