A sector of a circle of radius 6cm subtends an angle in of 105 at the centre of the circle. Calculate I)the length of the minor
Ii)Perimeter of the sector
Iii)the area of the sector[take pi =22/7

c

Step-by-step explanation:

the perimeter of the sector

Sorry dont know :(

Step-by-step explanation:

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
