## jollysailorbold 3 years ago Find the area of the shaded portion in the square. (assuming the central point of the arc is the corresponding corner) https://media.glynlyon.com/a_matgeo_2011/7/groupi57.gif

|dw:1335260783163:dw| it has to be plugged into this.

A=area of square-area of quarter circle with radius 6

is the website for knowing more

:| thanks for your time. but. that didn't quite help. at all. thank you though.

Area of shaded= area of square- area of sector $Area ~of ~shaded= (6)\times(6)-\frac{1}{2}r^2 \theta$ $Area ~of ~shaded= 36-\frac{1}{2}(6)^2 \frac{pi}{2}$ $Area ~of ~shaded= 36-\frac{1}{2}(6)^2 \frac{pi}{2}$ $Area ~of ~shaded= 7.722$

will be 36-9pi because 9pi is a quarter from area of this circle with radius 6 -area of square =6*6=36 - area circle = pir^2 =36pi - a quarter of area circle = 36pi/4 =9pi - area sheped =area square - quarter of area circle =36-9pi - if we consider pi=3,14 - so than area shaped = 36-28,26=7,74
