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
