Question

A circle of radius 21cm is divided into 6 equal sectors find the area of each of the sectors

Answer 1

Answer:

231 cm square

area of the circle=22/7 r square

as the circle is divided into 6 equal sectors,

area of each sector=22/7 × 21 × 21/6

=231 cm square

Answer 2

Answer:

Step-by-step explanation:

From the above question,

A circle of radius 21cm is divided into 6 equal sectors, we have to find the area of each of the sectors.

             The circle of radius 21cm has an place of π$r^2$

                                            = π(21cm)$.^{2}$

                                            = 441π c$m^2$.

Dividing it into 6 equal sectors skill dividing the circle into 6 equal angles of 360/6 = 60 ranges each.

The vicinity of every region is consequently (60/360) instances the location of the circle:

Area of every quarter = (60/360) × 441π c$m^2$

                                    = (1/6) × 441π c$m^2$

                                    = 73.5π c$m^2$

                                     = 229.94 c$m^2$ (approx)

Therefore, the place of every of the 6 sectors is about 229.94 c$m^2$.
