Correct Answer - Option 1 : 154 cm
2
Given:
Radius of chord AB of circle = 14 cm
Angle at the centre of the circle = 90
Concept:
Simply we used the concept of area of the sector.
Formula Used:
Area of sector = \(\frac{\theta }{{360}} \times \;\pi {r^2}\)
Calculation:
Area of minor sector = \(\frac{{90^\circ }}{{360^\circ }}\; \times \;\frac{{22}}{7}\; \times {14^2}\)
⇒ Area of minor sector = \(\frac{{90^\circ }}{{360^\circ }}\; \times \;\frac{{22}}{7}\; \times {14^2}\)
⇒ Area of minor sector = 154 cm2
∴ Area of minor sector is 154 cm2
