Answer 2

area of the sector or area of the triangle?

Answer 3

i think triangle

Answer 4

Tip: OA and OB are radius so OA = OB = 6

You can calculate the area using 2 sides and an angle between OR using pythagoras theorem.

Answer 5

if it's the triangle, you can just use A = (1/2)6^2*sin(60)

if it's the sector, A=(1/2)r^2*(pi/3)

and if it's that part of the sector not including the triangle part, then just subtract.
