Question

A circle of radios 70 cm is divided into 8 equal sector.find the area of the sectors.​

Answer 1

Step-by-step explanation:

r = 70cm

Area of the Circle = π r2

= $\frac{22}{7} \times {70}^{2}$

$= \frac{22}{7} \times 70 \times 70$

$= 22 \times 10 \times 70$

$= 15400 \: {cm}^{2}$

Circle is divided into 8 sectors i.e. 8 equal parts

Therefore, Area of one sector = 15400/8 = 1925 cm2

Answer 2

area of circle is πr²

here r =70cm

area of circle =3.14×[70]²

A=15386cm²

• circle divided by 8 equal sector then area of a secter is

area of circle/8

15386/8=1924.25 cm²
