Question

ABand CDare two chords of a circle on the same side of the centre such that AB= 8 cm, CD = 10 cm and AB || CD. If the distance between AB and CDis 2 cm, then find the radius of the circle

Answer 1

Explanation:

Radius = 4.5 cm

Reason - ( 1/2 of seg AB = 1/2×8 = 4, 1/2 of seg CD = 1/2 × 10 = 5, Therefore, The Radius = 5 + 4 = 9 ÷ 2 = 4.5 cm.)
