A circle with radius \pink{9}9start color #ff00af, 9, end color #ff00af has a sector with a central angle of \purple{120^\circ}1

GrogVix [38]

Answer:

Area of sector = 84.861

Step-by-step explanation:

Given

The radius of the circle = 9

central angle of sector = $120^{o}$

value of pi π = 3.143

To find : the area of sector = ?

We know that the formula to calculate area of sector is given as:

area of sector = (π $r^{2}$ Θ)/ $360^{o}$

where, r is radius and Θ is the central angle of the sector

Substituting the known values in above formula, we get

area of sector = (3.143 x $9^{2}$ x $120^{o}$ ) / $360^{o}$

= 84.861

Hence area of sector is 84.861
