Question

(15pts) Given the diagram: what is the area of the shaded sector corresponding to AB, rounded to two decimal places?

Answer 1

Area of a Sector of Circle = (θ/360º) × πr²

• θ = angle subtended at the center
• r = radius of the circle

`area \: = \: (70)/(360) * (22)/(7) * 10 {}^(2) \\ = 61.11`

on rounding off to two decimal places:-

61 Sq. units
