CellusFind the length of arc AB. Use 3.14 for n.Round to the nearest tenth.5 79 cm66 49D[? ]cmEnter

Answer 1

To calculate the segment AB you have to use the following formula

`AB=\text{ }(\theta)/(180º)\pi R`

θ represents the central angle θ =90º

R represents the radius R= 7.9cm

`AB=(90)/(180)\cdot314\cdot7.9=\text{12.403cm}`

The length of segment AB= 12.403cm
