Question

Two parallel lines touch the circle at points A and B . If the area of the circle is 36
Ti cm ?,then the length of AB is *
A 12 cm
B 6 cm
C 5 cm
D 36 cm

Answer 1

Step-by-step explanation:

HEY MATE.........

$area \: of \: Circle \: = \pi {r}^{2} = 36\pi \\ \\ = {r}^{2} = 36 \\ \\ r = 6cm \\ ab = 2r = 12cm$

HOPE IT HELPS YOU

Answer 2

A.12 cm

Step-by-step explanation:

AB will be diameter of circle.

Area = 36π cm

Area = πr^2

so, πr^2 = 36π cm

By solving, we get r = 6 CM

diameter = 2r

so, AB = diameter = 2 x 6 = 12 cm
