How much greater, in square inches, is the area of a circle of radius 20 inches than a circle of diameter 20 inches? express your answer in terms of pi.

  300π in²

Step-by-step explanation:

The circle with diameter 20 inches has a radius of 10 inches, so an area of ...

  A = πr² = π(10 in)² = 100π in²

The circle with a radius of 20 inches has an area of ...

  A = πr² = π(20 in)² = 400π in²

The larger circle is larger by ...

  (400π in²) -(100π in²) = 300π in²

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 )
