Question

Two parallel lines touch the circle at points A and
B respectively. If area of the circle is 251 cm
Then find the length of AB.

Answer 1

Answer:

hope it will answer correct

Step-by-step explanation:

the line does not meet at any point even extend in any direction the length of 25 so the answer is A14 B11

follow me

Answer 2

Answer:

Area = 25 pi cm^2 

AB are on lines parallel to each other

so AB is the diameter

Area = pi*r^2

25 pi = pir^2

r^2=25

r= 5 cm

AB = 10 cm 

-------------

Hypotenuse ^2= leg1^2+leg2^2

leg1 = 1.5 cmLeg2^2= 2 cm 

Hypotenuse^2 1.5 ^2 + 2 ^2

Hypotenuse^2 2.25 + 4

Hypotenuse^2 6.25

take the square root

Hypotenuse^2 2.5 cm

the diameter of the circle = 2.5 cm

radius = 1.25 

Area of circle = pi*r^2

Area =pi*1.25^2

Area = 4.90 cm^2
