Step-by-step explanation:
The ENTIRE 360° area of the circle is: Area = pi * r^2
Sector QRS is a FRACTION of this : 82° out of 360°
So area of QRS = 82/360 * pi * r^2 = 183.2 units^2
Answer:
183.2
Given,QR = 16 = Radius (r)
QRS = 82Use the formula for Area of sector of circle,Area of Sector QRS = (QRS/360) * pir^2
= 82/360 * pi*16^2 =
= 183. 189 = 183.2
