Area of a circle with a radius of 2 km

12.56km^2

Step-by-step explanation:

A=πr^2

π=3.14

r=2km

A=3.14×2×2

A=3.14×4

A=12.56km^2

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
