Question

Sketch the circle x²+y²=4,find area enclosed by y-axis and x=1

Answer 1

Answer:

√3 is the correct answer as per the question

Step-by-step explanation:

x=1 is given in the question therefore we should substitute 1 instead of x

1^2+y^2=4

so,

1+y^2=4

now bring 1 to right side

so the sign will become - 1

so y^2=4-1

y^2=3

therefore now bring the square to right side so the sign will become root

then,

y =√3
