Question

Circle O has a radius of 10, how do you find the length of an arc subtended by a central angle measuring 1.5 radians?

Answer 1

I tried this:

Explanation:

We can use the fact that the arc length `s` is related to the radius `r` and angle `theta` as:

`s=rtheta`

in your case:

`s=10*1.5=15` units

Answer 2

`"arc length "=15" cm"`

Explanation:

`• " length of arc "="circumference "xx"fraction of circle"`

`color(white)(xxxxxxxxxxxx)=cancel(2pir)xx1.5/cancel(2pi)`

`color(white)(xxxxxxxxxxxx)=10xx1.5=15" cm"`
