Do not double post.
A badge is made of a circle centre O, with radius 5cm and a chord AB of length 6cm creating a blue minor segment at the bottom. Give all your answers to 1 decimal place.
Find:
The angle AOB at the centre
The length of the minor arc AB
The area of the triangle AOB.
The area of the yellow major segment.
How do I do this? Please show the steps!! Thank you, I am so confused
Here is the screen shot of the question (it has a diagram) Please help me. thanks - also i just typed in random numbers to get the grey answers on the bottom

Hi Emily9873,
Your reference drawing is clear.
Draw the perpendicular bisector of AB meeting AB @M. Triangle OMB is a right triangle sides 3,4,5 from PYTheorem or knowing this special triangle
tan BOM =3/4. Arc tan 3/4=36.9 deg.AOB = 73,8deg You convert to radians
Can you do the rest?
