Question

Due today help pls!!!!

Answer 1

32.1m

Explanation:

`2\pi r*((x)/(360))=` arc length of sector of a circle

2 radii + arc length of a sector of a circle= perimeter of the sector

x=90 degrees

r=9

substitute values to find the arc length

`2(9)*\pi *((90)/(360) )= arc length\\arclength=14.1\\`
`14.1+2(9)=32.1`
