Question

two parallel line touch the circle at points A and B respectively. area of the circle is 4πcm2 then AB =?​

Answer 1

Answer:

since since two parallel lines touches the circle at point a and b . then maybe becomes the diameter this discussion on two parallel lines touch the circle at point a and b respectively if area of circle is 25πcm2, then a b= 10 CM

Answer 2

Answer:

hey here is your answer in above pic

pls mark it as brainliest

also pls refer the reference diagram uploaded by me in above pic

Step-by-step explanation:

so here area of adjoining circle=4pi cm square

so now here ab would be diameter

so now use area of circle =pi r square

so 4pi=pi r square

so eliminate pi on both sides we get

r square=4

ie taking square roots on both sides we get r=2 or r=-2

but as radius dimensions are negative r=-2 is absurd

thus r=2 cm

so we know that diameter=2×radius

thus ab is diameter,,

ab=2×2

ab=4

hence value of ab is 4 cm
