Question

If radius is 4 cm and angle of sector is 30°,find the area of corresponding major secto​

Answer 1

Answer:

Step-by-step explanation:

Radius = 4 cm

Area of sector = theta/360 × πr²

= 330/360 × 22/7 × 4 × 4

= 11/12 × 22/7 × 16

= 11/3 × 22/7 × 4

= 968/21

= 46.09 cm²

Hope this helps ☺️

Answer 2

Radius= 4cm

theta = 30°= a

(Bcs I don't have theta symbol in my phone)

Area = a × πr^2

360

30 × 3.14 × 4 ×4

360

4.18 cm^2

Area of major sector= Area of circle-area of sector

area of circle = πr^2

3.14 × 4 × 4

50.24 cm^2

Area of major sector = 50.24 - 4.18

46.06 cm^2
