Find area of shaded sector

Answer 1

Oh, dude, finding the area of a shaded sector is like finding the square footage of a slice of Pizza. You take the central angle of the sector, divide it by 360 (the total degrees in a circle), then multiply that by the area of the full circle. It's like calculating how much of the pizza you're getting - just with math instead of a slice of pepperoni.

Answer 2

theta (angle)

_____ X pi r squared

360

Note that if the angle is measured in radians, then you only need to do Θ*r².

A full circle is 360° or 2*pi radians

Answer 3

160 20ft
