Central angle of each sector = 360/ 7 = 51.4°

Sin (51.4 ° / 2) = (1.25/ 2 )/ r

Sin( 25.7°) = 0.625 r

0. 43/ 0.625 = r

r/2 = 0.69

d = 4(0.69) = 4( 0.69) = 2.79"

This is a trigonometry problem . You should draw a sector of 51.4° degree, and see the rissoles triangle

with 2 sides equal the radius, and the central angle of 51.4°.
