Determine 6415

Determine the distance of two parallel chords of lengths of 7 cm and 11 cm in a circle with a radius of 7 cm.

Correct answer:

x1 =  10.3923 cm
x2 =  1.7321 cm

Step-by-step explanation:

t1=7 cm t2=11 cm r=7 cm  a=r2(t1/2)2=72(7/2)26.0622 cm b=r2(t2/2)2=72(11/2)24.3301 cm  x1=a+b=6.0622+4.3301=6 3=10.3923 cm
x2=ab=6.06224.3301=3=1.7321 cm
