Answer 2

Now you can do it yourself..
\[l=r \theta \]
put the values and boom

Answer 3

or 15 pi= 47.12

Answer 4

is this right @ashutoshrcf

Answer 5

NO, see in the equation \[l=r \theta \] l is length of arc which we are going to find.
r is radius of the circle (here 10) and theta is angle subtended by arc in radians.
so length of arc is radius * theta
L=10*3pi/2
=15pi
YES, well done keep solving such questions for better grip on this topic.

Answer 6

Could you continue to watch over me work for a few more problems?
