I do not understand I need the method please please help me

L = 100 cm

Step-by-step explanation:

The length of a sector of a circle is a fraction of the entire circumference of the circle.

A circle has a circumference of 2πr. A full circle has a central angle of 360°.

The length of a sector of a circle is a fraction of the entire circumference.

The fraction is the central angle of the sector divided by 360°.

The length of a sector is given by the formula:

L = (n/360°)2πr

where L = length of sector,

n = degree measure of the central angle of the sector,

r = radius of the circle

In this case, the central angle of the sector is 155°, and the radius of the circle is 37 cm.

L = (155°/360°) × 2 × 3.14159 × 37 cm

L = 100 cm

choice b is correct
