Find the area of a circular segment of a circle of radius 7cm that sub tends a central angle of 35 degrees?

• Math -

area of sector/area of circle = 35/360
area of sector /49π = 7/72
area of sector = 343π/72

area of triangle with the chord as its base
= (1/2)(7)(7)sin35°
= (49/2)sin35 , Using area of triange = (1/2)(a)(b)sinØ
where a and b are sides with Ø the contained angle

area of segment = 343π/72 - (49/2)sin35°
= ....

you do the button-pushing if you need a decimal answer
