Question

Asap! find the length of the arc

Answer 1

B

Explanation:

the arc length is calculated as

arc = circumference of circle × fraction of circle

= 2πr ×
`(90)/(360)`

= 2π × 16 ×
`(1)/(4)`

= 2π × 16 ×
`(1)/(4)`

= 32π ×
`(1)/(4)`

= 8π ft

Answer 2

8π ft

Explanation:

Arc length = 2πr ( θ / 360 )

Here,

θ = 90

r = 90 ft

Arc length = 2πr ( θ / 360 )

Arc length = ( 2π * 16 ) ( 90 / 360 )

= ( 2π * 16 ) ( 1 / 4 )

= ( 2π * 16 )/4

= 2π * 4

Arc length = 8π ft
