Hey guys I'm struck on this question, it's the second question on the picture , the one about the sector of the circle. Any help would be greatly appreciated.
The answers for a. Is 4.77cm b. is 180cm^2 and c. Is 9.55cm if that helps
Thanks all :)

the length of the arc AA' will be your circumference of the circle of your cone.

the curved surface area will be the area of the sector.

it's asking for diameter.
